Vishay VIA2000SD

VIA2000SD is a high reliability reinforced isolated amplifier. It is a high performance differential output isolation amplifier suited for high precision isolated voltage sensing. The device is based on proprietary capacitive isolation technology and has a single-ended input signal range from 0.02V to 2V. The device has a high input impedance making it suitable for measurements across HV potential dividers. The device's unmatched CMTI of 100 kV/μs min. allows accurate measurements in the noisy environment. Applications include bus voltage monitoring, AC motor controls, power and solar inverters, uninterruptible power suppliers. Approved by UL, cUL, DIN EN 60747-5-5 (VDE 0884-5) and CQC.
