INA293 Overview
The INA293 is a high-precision current sense amplifier that can measure voltage drops across shunt resistors over a wide mon-mode range from 4 V to 110 V. The negative mon-mode voltage allows the device to operate below ground, thus acmodating precise measurement of recirculating currents in half-bridge applications. The bination of a low offset voltage, small gain error and high DC CMRR enables highly accurate...
