INA2181 Overview
The INA181, INA2181, and INA4181 (INAx181) current sense amplifiers are designed for costoptimized applications. These devices are part of a family of bidirectional, current-sense amplifiers (also called current-shunt monitors) that sense voltage drops across current-sense resistors at monmode voltages from 0.2 V to +26 V, independent of the supply voltage. The INAx181 family integrates a matched resistor gain...
