Question, comment or suggestion?# Operational Amplifiers (Op-amps)

## Our Take

Operational amplifiers, or op-amps, are a beautiful thing. They provide relatively high amplification with relatively low noise or distortion, are pretty darn cheap, flexible in their setups and applications, and they’re easy to use. These characteristics make op-amps extremely common in design and in real life.

## Book Definition

A type of amplifier that has very high voltage gain, very high input impedance, very low output impedance, and good rejection of common-mode signals.
