EVAL-AD5593RSDZ User Guide UG-756
GENERAL DESCRIPTION
This user guide details the operation of the evaluation board for
the AD5593R 8-channel, 12-bit, configurable ADC/DAC with
on-chip reference and SPI interface.
The evaluation board is designed to help customers quickly
prototype new AD5593R circuits and reduce design time.
The AD5593R operates from a single 2.7 V to 5.5 V supply and
incorporates an internal 2.5 V reference to give an output voltage
span of 2.5 V or 5 V. An external reference (a 2.5 V reference is
provided on the evaluation board) can also be used to give an
output from 0 V to VREF or 0 V to 2 × VREF.
Full data on the AD5593R can be found in the AD5593R data
sheet, available from Analog Devices and should be consulted in
conjunction with this user guide when using the evaluation board.
The evaluation board interfaces to the USB port of a PC via the
SDP board. Software is supplied with the evaluation board to
allow the user to program the AD5593R.
This evaluation board requires the E VA L -SDP-CB1Z board
(SDP-B controller board), which is available for order on the
Analog Devices website at www.analog.com.

GETTING STARTED
INSTALLING THE SOFTWARE
The evaluation kit for the AD5593R includes self-installing
software on a CD. The software is compatible with Windows®
XP, Windows Vista (32-bit version), and Windows 7 (32- and
64-bit versions). The software must be installed before
connecting the SDP board to the USB port of the PC to ensure
that the SDP board is recognized when it is connected to the PC.
To install the software, take the following steps:
1. Start the Windows operating system and insert the CD.
2. The installation software should open automatically. If it does
not open automatically, run the setup.exe file from the CD.
3. After installation is completed, power up the evaluation
board as described in the Power Supplies section.
4. Connect the evaluation board to the SDP board and connect
the SDP board into the PC using the USB cable included in
the box.
5. When the software detects the evaluation board, proceed
through any dialog boxes that appear to finalize the installation.
EVALUATION BOARD SETUP PROCEDURES
1. Connect the evaluation board to the SDP board, and connect
the USB cable between the SDP board and the PC.
2. Power the SDP and evaluation boards by connecting 6 V
to the J3 connector.

EVALUATION BOARD HARDWARE
POWER SUPPLIES
To use the evaluation board with the SDP board, a 6 V power
supply is required, which is connected to Connector J3. The
evaluation board can also be used without the SDP board. In this
case, J2 is the power supply input for the VDD supply. A separate
VLOGIC supply can be connected to J1 if required. LK11 selects
the source for the AD5593R VLOGIC supply.
Both AGND and DGND inputs are provided on the board. The
AGND and DGND planes are connected at one location close
to the AD5593R. It is recommended that AGND and DGND
not be connected elsewhere in the system to avoid ground loop
problems.
All supplies are decoupled to ground with 10 µF tantalum and
0.1 µF ceramic capacitors.

DIGITAL INPUT AND OUTPUT SIGNALS
When the SDP board is used to control the AD5593R
evaluation board, the digital input signals are applied to
Connector J4. When the SDP board is not being used, digital
signals should be applied to the 10-way header, J5.
ANALOG INPUT AND OUTPUT SIGNALS
The I/O pins of the AD5593R are available on SMB connectors,
I/O0 to I/O7. These will be analog inputs or outputs depending
on whether the I/O pins are configured as ADCs or DACs,
respectively. I/O0 to I/O7 will be digital inputs or outputs if the
I/O pins are configured as GPIOs.

LINK CONFIGURATION OPTIONS
A number of link options are incorporated in the evaluation
board and must be set for the required operating conditions
before using the board. The functions of these link options are
described in detail in Table 2.
SETUP CONDITIONS
Take care before applying power and signals to the evaluation
board to ensure that all link positions are as required by the
operating mode. There are two modes in which to operate the
evaluation board. The evaluation board can be operated in SDP
controlled mode to be used with the SDP board, or the
evaluation board can be used in standalone mode.
Table 2 shows the default positions in which the links are set
when the evaluation board is packaged. When the board is
shipped, it is assumed that you are going to operate the
evaluation board with the SDP board (SDP controlled mode).

Position A selects the on-board 2.5 V reference as the reference source.
Position B selects an off board voltage reference via the EXT_REF connector. This option should also be
selected if the internal reference is to be used.

EVALUATION BOARD CIRCUITRY
The AD5593R evaluation board allows the function and
performance of the AD5593R to be easily tested. The evaluation
board contains two voltage regulators, which generate the
analog and digital power supplies and also power the SDP
board if it is connected. The two regulators are powered via a
6 V supply attached to Connector J3. Alternatively, a separate
supply can be attached via Connector J2. An optional VLOGIC
supply can be connected to J1 if required.
Control of the AD5593R is typically performed by the SDP
board, which is attached to J4. The SDP board allows the
software provided with the kit to be to used configure the
AD5593R and write/read data to/from the AD5593R.
When the SDP is not required, the control signals can be
applied to the AD5593R by connecting them to the relevant
pins on Connector J5.
In addition to the on-chip reference of the AD5593R an
external, 2.5 V reference is also provided and can be connected
to the AD5593R reference input/output pin (VREF) using LK3.

HOW TO USE THE SOFTWARE
STARTING THE SOFTWARE
To run the program, do the following:
3. Connect the evaluation board to the SDP board, and connect
the USB cable between the SDP board and the PC.
4. Power the SDP board and evaluation board by connecting
6 V to the J3 connector.
5. Click Start > All Programs > Analog Devices > AD5593R
> AD5593R Evaluation Software. When the software
connects to the evaluation board, the message shown in
Figure 3 displays.
Figure 3. Connection Message
If the SDP board is not connected to the USB port when
the software is launched, a connectivity error displays (see
Figure 4). Simply connect the evaluation board to the USB
port of the PC, wait a few seconds, click Rescan, and follow
the instructions.
Figure 4. Connectivity Error
Alternatively, the software can be used without an evaluation
board. The software runs in simulation mode displaying expected
outputs based on the input data. When the software runs, the
user is first prompted to configure the AD5593R I/O pins as
shown in Figure 5. The main window of the AD5593R
evaluation software then opens, as shown in Figure 6. The user
can click on the block diagram to access the DAC, ADC, and
GPIO functions as well as other options such as enabling the
internal reference.

DAC TAB
The DAC tab (see Figure 7) gives the user access to the DAC
functions. Each DAC has its own numeric control where a value
can be loaded to the appropriate DAC. Clicking Update DAC
Registers will load the data appropriately as determined by the
setting of the LDAC Mode control box.
ADC TAB
The ADC tab (see Figure 8) allows the user to select ADC
channels on which to perform conversions. The REPEAT
SEQUENCE checkbox should be set to take multiple samples.
The user can select the number of samples per channel and the
sample frequency. Clicking Take Samples will program the
AD5593R for the desired sequence and take the appropriate
number of samples. The data collected from the AD5593R is
split into separate channels and displayed on the graph as a
voltage. The user has the option to save the data to a comma
delimited spreadsheet file.

GPIO TAB
The GPIO tab allows the user to set the output levels for pins
set as general-purpose outputs and read the levels of pins set as
general-purpose inputs (see Figure 9).
SIMPLE CONTROLS TAB
The Simple Controls tab allows the user to enter 24-bit values
directly into the Write Array control. The 24-bit values are
configured as the Pointer Byte followed by the most significant
and least significant bytes respectively (see Figure 10).
These values can then be written to the AD5593R by clicking
the Write Data button. Data can be read from the AD5593R
registers using the Read Data button. The pointer byte
determines which register is to be read and the data appears in
the Read Array numeric indicator.
Any commands sent to the AD5593R that change the config-
uration of the AD5593R will not be reflected in the other tabs.
