Vishay Semiconductors VIA0050DD Isolation Amplifier
Vishay Semiconductors VIA0050DD Isolation Amplifier is a high-performance differential output amplifier ideally suited for shunt-based current sensing. This amplifier has a low offset drift of typically 0.15μV/°C and a low gain drift of typically 15ppm/°C, which ensures good accuracy over the entire temperature range. The VIA0050DD with unmatched CMTI of 100kV/μs allows accurate measurements in a noisy environment. This isolation amplifier is halogen-free, Pb-free, and RoHS-compliant. The VIA0050DD amplifier is ideal for isolated current measurement in motor control, power supplies, wind energy storage systems, charging stations, EV powertrains, and inverters and converters.
