Vishay Intertechnology releases VIA series isolation amplifiers for industrial, automotive, and medical applications

Vishay Intertechnology  announced the launch of the VIA0050DD, VIA0250DD, and VIA2000SD isolation amplifiers in Malvern, Pennsylvania. These devices are designed for industrial, automotive, and medical applications requiring high precision, reliability, and compact size.
The VIA series features a typical common-mode transient immunity (CMTI) of 150 kV/μs, a gain error of ±0.05%, and a gain drift of 15 ppm/°C, supporting calibration-free measurements across a temperature range of -40°C to +125°C. With a bandwidth of 400 kHz, the amplifiers enable faster measurements than traditional opto-based isolation amplifiers. They include low offset error and drift, reinforced isolation, and built-in diagnostics for precise current and voltage measurements, with common mode voltage detection to prevent failures.
The VIA0050DD, a capacitive isolation amplifier, has a minimum CMTI of 100 kV/μs and a differential input voltage of ±50 mV, suitable for precision current measurements in space-constrained applications like power inverters, battery energy storage systems, motor phase current sensing, and industrial motor controls. The VIA0250DD, with a differential input voltage of ±250 mV, supports both current and voltage measurements. The VIA2000SD, offering a linear differential input voltage range of 0.02 V to 2 V, is designed for high-fide...
