Difference amplifier

The differential amplifier is a closed-loop control technology component. An output signal/potential is generated at output 3, which corresponds to the difference between the two input signals/potentials at inputs 1 (w) and 2 (x). In the field of closed-loop control technology, the differential amplifier is used to determine deviation. In order to keep circuit wiring as straightforward as possible, required earthing (0 V) and supply voltage are not led out as terminals, but rather wired internally.
