An ideal op-amp should have the following properties:

Infinite open-loop gain G = vout/'vin.

Infinite input impedance Rin,

Zero input current.

Zero input offset voltage.

Infinite voltage range available at the output.

Infinite bandwidth.

Infinite slew rate.

Zero output impedance Rout.

Zero noise.

Infinite Common-mode rejection ratio (CMRR).

Infinite Power supply rejection ratio.
