Instrumentation Amplifier
Instrumentation amplifier is a switched gain precision operation amplifier. This is used for precise and accurate, low noise differential signal acquisition. 4mm sockets are used for the input signal. It can be interfaced with a wide range of sensors. It can take small voltage changes from a sensor and make those changes large enough to be measured using CRO. It is not able to drive a low impedance load such as a loudspeaker or relay. The output can be read on CRO. Digital multimeter may also be used to read the output. With switched gain of 5 to 1000, it can handle signal inputs over a very wide range making it suitable for almost all applications.
