Question

Which of the following is not the property of the instrumentational amplifier?

(a) Extremely high input impedance

(b) Low bias and offset currents

(c) High slew rate

(d) Very low CMRR

I got this question by my school teacher while I was bunking the class.

This interesting question is from Biomedical Signal Analysis and Processing Techniques topic in section Recording System of Biomedical Instrumentation

Answer 1

The correct choice is (d) Very low CMRR

The explanation: Instrumentational amplifiers have very high CMRR. The instrumentation amplifier offers the following advantages for its applications in the biomedical field. Some of them are like extremely high input impedance, low bias and offset currents, high slew rate.
