Instrumentation amplifier

An instrumentation amplifier is a type of special amplifier that is used to amplify very small electrical signals that are too small for regular amplifiers to pick up. It is like a super-sensitive amplifier that has multiple inputs and very high gain. It helps to amplify tiny electrical signals coming from things like sensors and detectors, so that scientists and engineers can measure and study them.
