741 IC OP-AMP – Operational Amplifier
An operational amplifier (often 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, an op-amp produces an output potential (relative to circuit ground) that is typically hundreds of thousands of times larger than the potential difference between its input terminals. Operational amplifiers had their origins in analogue computers, where they were used to perform mathematical operations in many linear, non-linear, and frequency-dependent circuits.
