Operational amplifier

Operational amplifier A μA741 integrated circuit, one of the most successful operational amplifiers. TypeIntegrated CircuitInventedKarl D. Swartzel Jr.First production1941Pin configurationV+: non-inverting inputV−: inverting inputVout: outputVS+: positive power supplyVS−: negative power supply The power supply pins (VS+ and VS−) can be labeled in different ways (See IC power supply pins). Often these pins are left out of the diagram for clarity, and the power configuration is described or assumed from the circuit.Electronic symbol
Circuit diagram symbol for an op-amp. Pins are labeled as listed above. An operational amplifier (op-amp) is a DC-coupled high-gain electronic voltage amplifier with a differential input and, usually, a single-ended output.[1] 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.[2]
