Define frequency response of an op-amp.

PCBWay

Answer: The frequency response of an op-amp is the graph of its open loop gain versus frequency. The open loop gain is generally expressed in dB and frequency is plotted on the logarithmic scale. Ideally the open loop gain of the op-amp is expected to remain constant irrespective of frequency. That means ideally the bandwidth of op-amp should be infinite but practically it is not so.
