Characteristics of practical op amp
WebAn “ideal” or perfect operational amplifier is a device with certain special characteristics such as infinite open-loop gain AO, infinite input resistance RIN, zero output resistance ROUT, infinite bandwidth 0 to ∞ and zero offset (the output is … WebAn operational amplifier commonly known as op-amp is a two-input single-output differential voltage amplifier which is characterized by high gain, high input impedance and low output impedance. The operational amplifier is called so because it has its origins in analog computers, and was mainly used to perform mathematical operations.
