Principle of Operation of NJM082M

An NJM082M op-amp consists of four differential amplifiers connected together in an inverting configuration. To achieve the desired gain, feedback resistors are placed around the differential amplifiers. These feedback networks provide the gain, offset and frequency response of the op-amp. The op-amp is powered by a two-pole power supply, also known as a dual rail power supply, which provides both positive and negative voltages. A common current source supplies the differential amplifiers with a constant current, which is determined by the current mirroring circuit. The current source also provides phase compensation for the op-amp, ensuring stable and uniform gain.
