INSTRUMENTATION AMPLIFIER
Instrumentation Amplifier (In-Amp) forms the basic
component of every measuring instrument and testing
equipment. Instrumentation Amplifier is a type of Differential
Amplifier which offers high Common-Mode Rejection.
It is available in integrated circuit form and can be built using
Op-amps and Resistors which have very low tolerance value
( Precision Resistors).
Instrumentation Amplifiers are basically used to amplify small
differential signals.

The Amplifier provides the most important function of
Common-Mode Rejection (CMR). It cancels out any
signals that have the same potential on both inputs.
The signals that have a potential difference between the
inputs get amplified.
An Instrumentation Amplifier is used for low-frequency
signals (≪1 MHz) to provide a large amount of Gain. It
amplifies the input signal rejecting Common-Mode Noise
that is present in the input signal.
