The INA2181A1QDGSRQ1 current sense amplifier is designed for a cost-optimized solution. These devices are a family of bidirectional current-sense amplifiers (also known as current-shunt monitors) that sense voltage drops across current-sense resistors at common-mode voltages ranging from –0.2V to +26V, independent of the supply voltage. The INAx181-Q1 family integrates a matched resistor gain network with four fixed-gain device options: 20V/V, 50V/V, 100V/V, or 200V/V. This matched gain resistor network minimizes gain error and reduces temperature drift.

These devices operate from a single 2.7V to 5.5V supply. The single-channel INA181-Q1 draws a maximum of 260 µA of supply current; the dual-channel INA2181-Q1 draws a maximum of 500 µA; and the quad-channel INA4181-Q1 draws a maximum of 900 µA.
