Product Overview
The INA180 is the single-channel member of Texas Instruments' INA180, INA2180, and INA4180 low- and high-side voltage-output current-sense amplifier family. It is categorized under Signal_Chain and is specified for sensing across a current-sense resistor with a common-mode voltage range from -0.2 V to +26 V, independent of the supply voltage.
The family supports single-supply operation from 2.7 V to 5.5 V and gain options of 20 V/V, 50 V/V, 100 V/V, and 200 V/V. Electrical limits include 350 kHz bandwidth for A1 devices, 2 V/µs output slew rate, ±150 µV maximum offset at VCM = 0 V, ±500 µV maximum offset at VCM = 12 V, 1 µV/°C maximum offset drift, and ±1% maximum gain error.
The INA180 uses a 5-pin SOT-23 package measuring 2.90 mm x 1.60 mm, with INA180A devices using pinout A and INA180B devices using pinout B. Related family options include the dual-channel INA2180 in 8-pin VSSOP or WSON packages and the quad-channel INA4180 in a 14-pin TSSOP package.
