Op-Amp(Operational Amplifier)
Operational Amplifier commonly known as Op-Amp, is a linear elcectronic device having three terminals, two high impedence input and one output terminal
Op-Amp can perform multiple function when attached to diffrent feedback combinations like resistive,
capacitive or both.
Generally it is used as voltage amplifier and the output voltage of the Op-Amp is the diffrence between the voltages at its two input terminals.
Op-Amp shows some properties that make it an ideal amplifier,
its open loop gain and input impedance is infinite (i.e.,practically very high), Output impedance and offset voltage is zero(i.e.,practically very low) and bandwidth is infinite(i.e.,practically limitted to frequency where its gain become unity).
