An instrumentation amplifier (InAmp) is an integrated circuit or operational amplifier topology that has high input impedance differential inputs and a low impedance single-sided output. Their ability to accurately extract a small signal in the presence of a large common mode makes these INAs ideal for sensor amplification. Content is provided "as is" by TI and community contributors and does not constitute TI specifications. 1.

An instrumentation amplifier (INA) is a very special type of differential input amplifier; its primary focus is to provide differential gain and high common-mode rejection. Change category view. Instrumentation amplifiers are precision devices having a high input impedance, a low output impedance, a high common-mode rejection ratio, a low level of self-generated noise and a low offset drift. The CMMR value of AD624 is 130dB when the gain is 500 and the maximum non-linearity obtained at unity gain is 0.0001%. This page was last edited on 14 January 2021, at 20:47. The input impedance of the circuit is increased over that of the op-amp alone. Instead of using uA741 you can use any opamp but the power supply voltage must be changed according to the op amp. So I am thinking to use an instrumentation amplifier instead of complete front end solution. An IC instrumentation amplifier typically contains closely matched laser-trimmed resistors, and therefore offers excellent common-mode rejection. d. All of the above A successful handyman will strive to have a vast array of tools, and know how and when to use each one.
