Operational amplifiers

An operational amplifier (often called op-amp or opamp) is a DC-coupled high-gain electronic voltage amplifier with a differential input and, usually, a single-ended output. In this configuration, and op-amp produces an output potential (relative to circuit ground) that is typically hundreds of thousands times larger than the potential difference between its input terminals.
