Vishay Semiconductors VIA2000SD Isolation Amplifier
Vishay Semiconductors VIA2000SD Isolation Amplifier is based on capacitive isolation technology and has a single-ended input signal range from 0.02V to 2V. This amplifier is a high-performance differential output isolation amplifier suited for high-precision isolated voltage sensing. The VIA2000SD amplifier with an unmatched CMTI of 100kV/μs minimum, allows accurate measurements in noisy environments. This amplifier operates at a temperature range of -40°C to 125°C and a bandwidth of a typical 400kHz frequency. The amplifier is RoHS-compliant and halogen-free. This isolation amplifier is ideal for bus voltage monitoring, AC motor controls, power and solar inverters, and uninterruptible power suppliers.
