How many op amps do you need for an instrumentation amplifier?
The op-amp instrumentation amplifier circuit that I am using is given below. The circuit requires three op-amps all together; I have used two LM358 ICs. The LM358 is a dual package op-amp that is it has two op-amps in one package so we need two of them for our circuit.

What are the advantages of an instrumentation amplifier?
Advantages of Three Op-amp Instrumentation Amplifier The gain of a three op-amp instrumentation amplifier circuit can be easily varied and controlled by adjusting the value of Rgain without changing the circuit structure. The gain of the amplifier depends only on the external resistors used.

How are op amps used in an IC?
Op-amps can also be used to build Voltage adder and voltage Subtractor circuit. What is an Instrumentation Amplifier IC? Apart from normal op-amps IC we have some special type of amplifiers for Instrumentation amplifier like INA114 IC. It is nothing more than few normal op-amps combined together for certain specific applications.
How to calculate the output voltage of an instrumentation amplifier?
The output voltage of the Instrumentation amplifier circuit can be calculated using the below formulae. Where, R = Resistor value the circuit. Here R = R2=R3=R4=R5=R6=R7 which is 10k
Which is a special implementation of operational amplifiers?
A special implementation of Operational Amplifiers is the Instrumentation Amplifier, a type of Differential Amplifier with Input Buffer Amplifier. In this tutorial, we will learn about few important Instrumentation Amplifier Basics and Applications and also the circuit and working of a three Op-amp Instrumentation Amplifier.
