What is Instrumentation amplifier?

A differential amplifier, typically built from three op-amps, with high input impedance and high CMRR. It amplifies small differential signals from sensors with high accuracy.

Field: Analog and electronic circuits

Instrumentation amplifier in the explanations

An instrumentation amplifier uses two input op-amps for high input impedance and gain and a third differential stage to reject common-mode signals, with CMRR that can exceed 100 dB.
