The main function of an instrumentation amplifier is to
Show Hint
Instrumentation amplifiers are widely used with sensors because they provide
\[
\boxed{\text{High CMRR + High input impedance + Accurate amplification}.}
\]

- Increase frequency
- Reduce noise and amplify small signals
- Convert AC to DC
- Measure resistance
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Recall the purpose of an instrumentation amplifier.
An instrumentation amplifier provides
- high input impedance,
- high common-mode rejection ratio (CMRR),
- accurate amplification of low-level signals.
Step 2: Choose the correct function. Its primary purpose is to \[ \boxed{\text{Reduce noise and amplify small signals}.} \] Therefore, \[ \boxed{(B)} \] is the correct answer.
