The amplifiers give safe and accurate current and voltage readings. They work fast, save space, and handle heat and noise in power and motor systems.
Vishay Intertechnology has introduced three new isolation amplifiers — VIA0050DD, VIA0250DD, and VIA2000SD — built for industrial, automotive, and medical systems where precision, reliability, and compact size matter.
These amplifiers offer high thermal stability and accurate signal measurement, featuring a typical common-mode transient immunity (CMTI) of 150 kV/μs. Their low gain error (±0.05%) and minimal gain drift (15 ppm/°C typical) ensure consistent performance without recalibration. With 400 kHz bandwidth, they deliver faster data acquisition than traditional opto-based solutions.
Each model includes low offset error and drift, reinforced isolation, and built-in diagnostics for reliable current and voltage measurements. Common-mode voltage detection adds protection against measurement failures. They’re also designed to work with Vishay’s WSBE shunts across a wide -40°C to +125°C range.
- VIA0050DD: Designed for tight spaces and low power use, it supports ±50 mV differential input and 100 kV/μs minimum CMTI. Ideal for isolated current sensing in power inverters, motor controls, and battery storage systems.
- VIA0250DD: With a wider ±250 mV input range, it enables both current and voltage isolation in applications needing broader measurement coverage.
- VIA2000SD: Offers the highest signal-to-noise ratio and bandwidth in the series, handling input from 0.02 V to 2 V. It is well-suited for precise voltage measurements in systems like UPS and bus voltage monitoring.
The VIA series supports high-accuracy sensing in bus voltage monitoring, AC motor control, solar inverters, and other power systems. It ensures reliable measurement across shunts and high-voltage dividers, even in noisy or extreme environments.
