If both inputs of the op amp shown in Fig. 1 are used simultaneously, then from equation, the output voltage is given by: Vo = Ao(V2 − V1) When V2 > V1 then Vo is positive, its maximum value being the positive supply voltage + Vs, which it has when (V2 > V1) ≥ Vs/Ao.

Operational Amplifiers (usually called ‘op amps’) were originally made from discrete components, being designed to solve mathematical equations electronically, by performing operations such as addition and division in analogue computers. Now produced in integrated-circuit (IC) form, op amps have many uses, with one of the most important being as a high-gain d.c. and a.c. voltage

Networks in which electrical energy is fed in at one pair of terminals and taken out at a second pair of terminals are called two port networks. The network between the input port and the output port is a transmission network for which a known relationship exists between the input and output currents and voltages.
