| Ideal | Nonideal |
|---|---|
| Infinite input impedance | Input impedance of about 1M Ω for IC op amps; as much as 10 12Ω for op amps with field effect transistor |
| Infinite open-loop gain for the differential signal | Open-loop gain typically between 104and 106 |
| Zero output impedance | Output impedance typically between 1 and 100 Ω |
| Infinite bandwidth | Bandwidth typically limited by the designer to avoid oscillation |
