There are many characteristics of an op-amp. But what are the important characteristics of an ideal operational amplifier?
The following are crucial qualities of a perfect op amp:
- Infinite voltage gain in an open loop.
- Infinite resistance to input.
- Zero resistance to output.
- Offset voltage is zero.
- Endless bandwidth.
- Unending CMRR.
- Infinite slew rate.
- Power supply rejection ratio is zero.
