Instrumentation amplifiers - the next level of precision signal conditioning

Integrated resistor networks maximize accuracy and space efficiency

Our portfolio of instrumentation amplifiers helps engineers improve direct-current (DC) accuracy and reduce system power while maintaining low distortion. Our proprietary thin-film technology allows for precise resistor matching and space savings.

Low noise (≤10nV/√Hz)

Achieve lower distortion and higher precision with ultra-low noise

Low offset (≤100µV)

Improve DC accuracy with low offset and high-precision performance

Low power (≤500µA)

Reduce system power without compromising performance

High voltage (≥12V)

Maximize input signal range for precision applications with a wider supply voltage
