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 increasing efficiency and maintaining low distortion. Our proprietary thin-film technology allows for precise resistor matching and space savings.
High voltage (≥12V)
Maximize input signal range for precision applications with a wider supply voltage
