Vishay VIA0050DD

VIA0050DD is a high thermal stability isolation amplifier. It is a high-performance differential output isolated amplifier ideally suited for shunt-based current sensing. The device is based on proprietary capacitive isolation technology and has a linear differential input signal range of ±50mV (±64mV full scale). The device has a fixed gain of 41 and provides a differential analogue output. It is suitable for isolated current measurement in motor control applications, power supplies, solar and wind energy storage systems, charging stations and EV powertrain, inverter and converters.
