Product Overview
The INA180A3IDBVR is a Texas Instruments single-channel current-sense amplifier for Signal_Chain designs. It is part of the INAx180 family of low-side and high-side voltage-output current-sense amplifiers and uses the A3 fixed-gain option, giving this selected part a 100 V/V gain.
The device senses voltage drops across current-sense resistors from -0.2 V to +26 V common-mode, independent of the 2.7 V to 5.5 V supply voltage. Listed electrical parameters include ±150 µV maximum input offset at VCM = 0 V, ±500 µV maximum input offset at VCM = 12 V, ±1% maximum gain error, 1 µV/°C maximum offset drift, and 2 V/µs output slew rate.
The INA180A3IDBVR is supplied in the DBV 5-pin SOT-23 package with a 2.90 mm x 1.60 mm nominal body. Pinout A assigns OUT to pin 1, GND to pin 2, IN+ to pin 3, IN- to pin 4, and VS to pin 5. The IN+ and IN- connections support both high-side and low-side sense-resistor placement.
