Can anyone help me,

Why Op Amp is called "Operational Amplifier" ?

Is Instrumentation Amplifier is not Operational Amplifier?

Please explain in your own words.

Thanks,
Baig.

According to my understanding and knowledge,
Op Amp is abbreviation of operational amplifier, which means performing some mathematical operations on input signal and performing amplification i.e. adding or subtracting two signals and amplifying their result just as in mixer circuits etc.

Until my info, all instrumentation amplifier contains op-amps as basic building blocks just like logic gates in digital circuits. And the differential amplifier is the basic building block of op-amps. So, the instrumentation amplifier generally contains op-amp circuits to create specialized amplifier modified/tailored for particular application like audio amplifier, RF amplifier etc.

Thanks

The operational amplifier circuit first came into existence as a basic building block in analog computers. It was referred to as operational because it was used to implement the mathematical operations of integration, differentiation, addition, sign changing, and scaling. In recent years, the range of application has broadened beyond implementing mathematical operations; however, the original name for the circuit persists. Engineers and technicians have a penchant for creating technical jargon; hence the operational amplifier is widely known as the op amp.
