Question

Quizplus · Accepted Answer

A voltage follower is used as an isolation amplifier, low pass filter, unity gain amplifier, and non-inverting amplifier due to its characteristics of high input impedance, low output impedance, and unity gain. However, it is not suitable as a comparator because it does not compare voltages but rather outputs a voltage that follows its input.
