3 Description
The INA193INA198 family of current shunt monitors
with voltage output can sense drops across shunts at
common-mode voltages from 16 V to +80 V,
independent of the INA19x supply voltage. They are
available with three output voltage scales: 20 V/V, 50
V/V, and 100 V/V. The 500 kHz bandwidth simplifies
use in current control loops. The INA193INA195
devices provide identical functions but alternative pin
configurations to the INA196INA198 devices,
respectively.
The INA193INA198 devices operate from a single
2.7-V to 18-V supply, drawing a maximum of 900 μA
of supply current. They are specified over the
extended operating temperature range (40°C to
+125°C), and are offered in a space-saving SOT-23
package.

8 Detailed Description
8.1 Overview
The INA193INA198 family of current shunt monitors with voltage output can sense drops across shunts at
common-mode voltages from 16 V to +80 V, independent of the INA19x supply voltage. They are available with
three output voltage scales: 20 V/V, 50 V/V, and 100 V/V. The 500-kHz bandwidth simplifies use in current
control loops. The INA193INA195 devices provide identical functions but alternative pin configurations to the
INA196INA198, respectively.
The INA193INA198 devices operate from a single +2.7-V to +18-V supply, drawing a maximum of 900 μA of
supply current. They are specified over the extended operating temperature range (40°C to +125°C), and are
offered in a space-saving SOT-23 package.

8.3 Feature Description
8.3.1 Basic Connection
Figure 20 shows the basic connection of the INA193-INA198. To minimize any resistance in series with the shunt
resistance, connect the input pins, VIN+ and VIN, as closely as possible to the shunt resistor.
Power-supply bypass capacitors are required for stability. Applications with noisy or high impedance power
supplies may require additional decoupling capacitors to reject power-supply noise. Connect bypass capacitors
close to the device pins.
Figure 20. INA193-INA198 Basic Connection
8.3.2 Selecting RS
The value chosen for the shunt resistor, RS, depends on the application and is a compromise between small-
signal accuracy and maximum permissible voltage loss in the measurement line. High values of RSprovide better
accuracy at lower currents by minimizing the effects of offset, while low values of RSminimize voltage loss in the
supply line. For most applications, best performance is attained with an RSvalue that provides a full-scale shunt
voltage range of 50 mV to 100 mV. Maximum input voltage for accurate measurements is 500 mV.
8.3.3 Inside the INA193-INA198
The INA193-INA198 devices use a new, unique internal circuit topology that provides common-mode range
extending from 16 to 80 V while operating from a single power supply. The common-mode rejection in a classic
instrumentation amplifier approach is limited by the requirement for accurate resistor matching. By converting the
induced input voltage to a current, the INA193-INA198 devices provide common-mode rejection that is no longer
a function of closely matched resistor values, providing the enhanced performance necessary for such a wide
common-mode range. A simplified diagram (shown in Figure 21) shows the basic circuit function. When the
common-mode voltage is positive, amplifier A2 is active.

Feature Description (continued)
The differential input voltage, (VIN+)(VIN) applied across RS, is converted to a current through a resistor. This
current is converted back to a voltage through RL, and then amplified by the output buffer amplifier. When the
common-mode voltage is negative, amplifier A1 is active. The differential input voltage, (VIN+)(VIN) applied
across RS, is converted to a current through a resistor. This current is sourced from a precision current mirror
whose output is directed into RLconverting the signal back into a voltage and amplified by the output buffer
amplifier. Patent-pending circuit architecture ensures smooth device operation, even during the transition period
where both amplifiers A1 and A2 are active.

8.4.1 Input Filtering
An obvious and straightforward location for filtering is at the output of the INA193-INA198 devices; however, this
location negates the advantage of the low output impedance of the internal buffer. The only other option for
filtering is at the input pins of the INA193-INA198 devices, which is complicated by the internal 5-kΩ+ 30% input
impedance; this is illustrated in Figure 25. Using the lowest possible resistor values minimizes both the initial shift
in gain and effects of tolerance. The effect on initial gain is given by Equation 1:

Total effect on gain error can be calculated by replacing the 5-kΩterm with 5 kΩ30%, (or 3.5 kΩ)or5kΩ+
30% (or 6.5 kΩ). The tolerance extremes of RFILT can also be inserted into the equation. If a pair of 100-Ω1%
resistors are used on the inputs, the initial gain error will be approximately 2%. Worst-case tolerance conditions
will always occur at the lower excursion of the internal 5-kΩresistor (3.5 kΩ), and the higher excursion of RFILT
3% in this case.
Note that the specified accuracy of the INA193-INA198 devices must then be combined in addition to these
tolerances. While this discussion treated accuracy worst-case conditions by combining the extremes of the
resistor values, it is appropriate to use geometric mean or root sum square calculations to total the effects of
accuracy variations.

8.4.2 Accuracy Variations as a Result of VSENSE and Common-Mode Voltage
The accuracy of the INA193INA198 current shunt monitors is a function of two main variables: VSENSE (VIN+
VIN) and common-mode voltage, VCM, relative to the supply voltage, VS. VCM is expressed as (VIN+ + VIN)/2;
however, in practice, VCM is seen as the voltage at VIN+ because the voltage drop across VSENSE is usually small.
This section addresses the accuracy of these specific operating regions:
Normal Case 1: VSENSE 20mV, VCM VS
Normal Case 2: VSENSE 20mV, VCM < VS
Low VSENSE Case 1: VSENSE < 20mV, 16V VCM < 0
Low VSENSE Case 2: VSENSE < 20mV, 0V VCM VS

Low VSENSE Case 3: VSENSE < 20mV, VS< VCM 80V
8.4.2.1 Normal Case 1: VSENSE 20mv, VCM VS
This region of operation provides the highest accuracy. Here, the input offset voltage is characterized and
measured using a two-step method. First, the gain is determined by Equation 2.
where:
VOUT1 = Output Voltage with VSENSE = 100mV
VOUT2 = Output Voltage with VSENSE = 20mV (2)
Then the offset voltage is measured at VSENSE = 100mV and referred to the input (RTI) of the current shunt
monitor, as shown in Equation 3.
(3)
In the Typical Characteristics, the Output Error vs Common-Mode Voltage curve (Figure 6) shows the highest
accuracy for this region of operation. In this plot, VS= 12 V; for VCM 12 V, the output error is at its minimum.
This case is also used to create the VSENSE 20-mV output specifications in the Electrical Characteristics table.
8.4.2.2 Normal Case 2: VSENSE 20mv, VCM < VS
This region of operation has slightly less accuracy than Normal Case 1 as a result of the common-mode
operating area in which the part functions, as seen in the Output Error vs Common-Mode Voltage curve
(Figure 6). As noted, for this graph VS= 12 V; for VCM < 12 V, the Output Error increases as VCM becomes less
than 12 V, with a typical maximum error of 0.005% at the most negative VCM =16V.

8.4.2.3 Low VSENSE Case 1: VSENSE < 20mV, 16v VCM < 0; and Low VSENSE Case 3: VSENSE < 20mV, VS<
VCM 80V
Although the INA193INA198 family of devices are not designed for accurate operation in either of these
regions, some applications are exposed to these conditions; for example, when monitoring power supplies that
are switched on and off while VSis still applied to the INA193INA198 devices. It is important to know what the
behavior of the devices will be in these regions.
As VSENSE approaches 0 mV, in these VCM regions, the device output accuracy degrades. A larger-than-normal
offset can appear at the current shunt monitor output with a typical maximum value of VOUT = 300 mV for VSENSE
= 0 mV. As VSENSE approaches 20 mV, VOUT returns to the expected output value with accuracy as specified in
the Electrical Characteristics.Figure 26 illustrates this effect using the INA195 and INA198 devices (Gain = 100).
Figure 26. Example for Low VSENSE Cases 1 and 3 (INA195, INA198: Gain = 100)
8.4.2.4 Low VSENSE Case 2: VSENSE < 20 mV, 0 V VCM VS
This region of operation is the least accurate for the INA193INA198 family of devices. To achieve the wide input
common-mode voltage range, these devices use two op amp front ends in parallel. One op amp front end
operates in the positive input common-mode voltage range, and the other in the negative input region. For this
case, neither of these two internal amplifiers dominates and overall loop gain is very low. Within this region, VOUT
approaches voltages close to linear operation levels for Normal Case 2. This deviation from linear operation
becomes greatest the closer VSENSE approaches 0 V. Within this region, as VSENSE approaches 20 mV, device
operation is closer to that described by Normal Case 2. Figure 27 illustrates this behavior for the INA195 device.
The VOUT maximum peak for this case is tested by maintaining a constant VS, setting VSENSE = 0 mV and
sweeping VCM from 0 V to VS. The exact VCM at which VOUT peaks during this test varies from part to part, but the
VOUT maximum peak is tested to be less than the specified VOUT Tested Limit.

8.4.3 Shutdown
Because the INA193-INA198 devices consume a quiescent current less than 1 mA, they can be powered by
either the output of logic gates or by transistor switches to supply power. Use a totem-pole output buffer or gate
that can provide sufficient drive along with 0.1-μF bypass capacitor, preferably ceramic with good high-frequency
characteristics. This gate should have a supply voltage of 3 V or greater because the INA193-INA198 devices
require a minimum supply greater than 2.7 V. In addition to eliminating quiescent current, this gate also turns off
the 10-μA bias current present at each of the inputs. An example shutdown circuit is shown in Figure 28.

8.4.4 Transient Protection
The 16-V to +80-V common-mode range of the INA193-INA198 devices is ideal for withstanding automotive
fault conditions ranging from 12-V battery reversal up to 80-V transients, since no additional protective
components are needed up to those levels. In the event that the INA193-INA198 devices are exposed to
transients on the inputs in excess of its ratings, then external transient absorption with semiconductor transient
absorbers (zeners or Transzorbs) will be necessary. Use of MOVs or VDRs is not recommended except when
they are used in addition to a semiconductor transient absorber. Select the transient absorber such that it will
never allow the INA193-INA198 devices to be exposed to transients greater than +80 V (that is, allow for
transient absorber tolerance, as well as additional voltage due to transient absorber dynamic impedance).
Despite the use of internal zener-type ESD protection, the INA193-INA198 devices do not lend themselves to
using external resistors in series with the inputs because the internal gain resistors can vary up to ±30%. (If gain
accuracy is not important, then resistors can be added in series with the INA193-INA198 inputs with two equal
resistors on each input.)
8.4.5 Output Voltage Range
The output of the INA193-INA198 devices are accurate within the output voltage swing range set by the power-
supply pin, V+. This is best illustrated when using the INA195 or INA198 devices (which are both versions using
a gain of 100), where a 100-mV full-scale input from the shunt resistor requires an output voltage swing of +10 V,
and a power-supply voltage sufficient to achieve +10 V on the output.

9 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
9.1 Application Information
The INA193-INA198 devices measure the voltage developed across a current-sensing resistor when current
passes through it. The ability to have shunt common-mode voltages from 16-V to +80-V drive and control the
output signal with Vs offers multiple configurations, as discussed throughout this section.
9.2 Typical Application
The device is a unidirectional, current-sense amplifier capable of measuring currents through a resistive shunt
with shunt common-mode voltages from 16 V to 80 V. Two devices can be configured for bidirectional
monitoring and is common in applications that include charging and discharging operations where the current
flow-through resistor can change directions.
Figure 29. Bi-Directional Current Monitoring
9.2.1 Design Requirements
Vsupply is set to 12 V, Vref at 2.5 V and a 10-mΩshunt. The accuracy of the current will typically be less than
0.5% for current greater than ±2 A. For current lower than ±2 A, the accuracy will vary; use the Device Functional
Modes section for accuracy considerations.

Typical Application (continued)
9.2.2 Detailed Design Procedure
The ability to measure this current flowing in both directions is enabled by adding a unity gain amplifier with a
VREF, as shown in Figure 29. The output then responds by increasing above VREF for positive differential signals
(relative to the IN – pin) and responds by decreasing below VREF for negative differential signals. This reference
voltage applied to the REF pin can be set anywhere between 0 V to V+. For bidirectional applications, VREF is
typically set at mid- scale for equal signal range in both current directions. In some cases, however, VREF is set
at a voltage other than mid-scale when the bidirectional current and corresponding output signal do not need to
be symmetrical.
9.2.3 Application Curve
An example output response of a bidirectional configuration is shown in Figure 30. With the REF pin connected
to a reference voltage, 2.5 V in this case, the output voltage is biased upwards by this reference level. The
output rises above the reference voltage for positive differential input signals and falls below the reference
voltage for negative differential input signals.
Figure 30. Output Voltage vs Shunt Input Current
10 Power Supply Recommendations
The input circuitry of the INA193-INA198 devices can accurately measure beyond its power-supply voltage, V+.
For example, the V+ power supply can be 5 V, whereas the load power-supply voltage is up to 80 V. The output
voltage range of the OUT terminal, however, is limited by the voltages on the power-supply pin.
11 Layout
11.1 Layout Guidelines
11.1.1 RFI and EMI
Attention to good layout practices is always recommended. Keep traces short and, when possible, use a printed
circuit board (PCB) ground plane with surface-mount components placed as close to the device pins as possible.
Small ceramic capacitors placed directly across amplifier inputs can reduce RFI/EMI sensitivity. PCB layout
should locate the amplifier as far away as possible from RFI sources. Sources can include other components in
the same system as the amplifier itself, such as inductors (particularly switched inductors handling a lot of current
and at high frequencies). RFI can generally be identified as a variation in offset voltage or DC signal levels with
changes in the interfering RF signal. If the amplifier cannot be located away from sources of radiation, shielding
may be needed. Twisting wire input leads makes them more resistant to RF fields. The difference in input pin
location of the INA193-INA195 devices versus the INA196-INA198 devices may provide different EMI
performance.

(1) The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.
(2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may
reference these types of products as "Pb-Free".
RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based
flame retardants must also meet the <=1000ppm threshold requirement.
(3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
(4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.
(5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation
of the previous line and the two combined represent the entire Device Marking for that device.
(6) Lead finish/Ball material - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead finish/Ball material values may wrap to two
lines if the finish value exceeds the maximum column width.
