Home Amplifiers Difference amplifiers


Difference amplifiers that give you everything you want and nothing you don't

Featuring precision-matched resistor networks for high accuracy and wide common-mode

Our difference amplifiers are optimized for high-input common-mode voltages and common-mode rejection ratios to measure small differential signals. Additionally, our difference amplifiers offer low-gain and gain drift errors for high-accuracy systems.

High common-mode voltage (≥100V)

Maximize input signal range with high common-mode voltage capability

High CMRR (≥80dB)

Reduce unwanted noise with a high common-mode-rejection ratio

Low offset (≤250µV)

Improve DC accuracy with low offset and high-precision performance
