DESCRIPTION
The VIA0050DD 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 ± 50 mV (± 64 mV full scale).
The device has a fixed gain of 41 and provides a differential
analog output.
The low offset drift typ. 0.15 μV/°C and low gain drift
typ. 15 ppm/°C ensures a good accuracy over the entire
temperature range. The devices unmatched CMTI of
100 kV/μs allows accurate measurements in the noisy
environment. FEATURES
