INA216A4YFFT Current Sense Amplifier



Texas Instruments' tiny, low power current sense amplifier for high side sensing

Texas Instruments INA216A4YFFT Current Sense Amplifier Texas Instruments' INA216A4 is a high-side voltage output current shunt monitor that can sense drops across shunts at common-mode voltages from +1.8V to +5.5V. The low offset of the Zerø-Drift architecture enables current sensing with maximum drops across the shunt as low as 10mV full-scale or with wide dynamic ranges of over 1000:1. This device operates from a single +1.8V to +5.5V power supply, drawing a maximum of 25µA of supply current. The INA216A4 is specified over the temperature range of -40°C to +125°C and offered in a chip-scale package.
