Product details

Current-sense amplifier for shunt-based monitoring

5 µV offset and 90 µA input bias

A 5 µV input offset voltage and 90 µA input bias current allow the INA240A3D to resolve microvolt-level shunt drops, which translates to accurate current measurement at low load currents. The 1.8 mA supply current keeps the quiescent draw low enough for always-on monitoring in battery-powered systems.
