General Description

The INA281 is a high-precision current sense amplifier that can measure voltage drops across shunt resistors over a wide common-mode range from –4 V to 110 V.

The negative common-mode voltage allows the device to operate below ground, thus accommodating precise measurement of recirculating currents in half-bridge applications.

The combination of a low offset voltage, small gain error and high DC CMRR enables highly accurate current measurement.
