Instrumentation Amplifier Explained (with Derivation)

In this video, the instrumentation amplifier has been explained with the derivation of the output voltage. And also in this video, it has been explained that how this instrumentation amplifier is superior to the normal differential amplifier (Difference amplifier) and in certain industrial applications why instrumentation amplifier is prefered (Because of high gain, high CMRR and high input impedance) over the differential amplifier. What is Instrumentation Amplifier: The instrumentation amplifier is one kind of differential amplifier which provides very high gain, high CMRR and high input impedance and it is designed for very specific applications. It is used in certain industrial applications (to amplify the output of the transducers) and in test and measurement equipment. Because of its high CMRR and high input impedance, it is prefered in the harsh environmental conditions where it is possible to have very large common mode noise or interference signals and very low input differential signals. The timestamps for the different topics covered in the video is given below: 0:19 What is Instrumentation Amplifier? 0:55 Why Instrumentation amplifier is prefered over the differential amplifier in certain applications 11:20 Instrumentation amplifier circuit explained with the derivation This video will be helpful to all the students of science and engineering to learn about the instrumentation amplifier.
