An operational amplifier (op-amp) is an integrated circuit (IC) that amplifies the difference in voltage between two inputs.
It has two terminals i.e. inverting and non-inverting terminals.
The output of the OP-AMP is:
\(V_{OUT}=A_V({V_{NI}-V_I})\)
Properties of OP-AMP
- High input impedance
- Low output impedance
- High CMRR
- High gain
- High slew rate
- Low input offset voltage
- High bandwidth
