What would be the characteristics of the ideal op-amp?

An ideal operational amplifier is a theoretical model used to simplify circuit analysis. It would draw absolutely zero current from the signal source, which dictates that it must have infinite input impedance. It must also be able to drive any load without a voltage drop, requiring zero output impedance. Furthermore, an ideal op-amp provides infinite open-loop voltage gain, allowing external feedback to precisely control the circuit's actual behavior. It also boasts a perfectly flat frequency response, amplifying all frequencies equally without distortion. Real-world op-amps only approximate these perfect characteristics.
