Q. What do you mean by Frequency Response?

As with all electronic circuits, op amps have limited frequency response. Because of the negative feedback of the circuit, the passband of an op-amp circuit is usually much larger than that of the op amp by itself. Typically with a given op amp, increasing the bandwidth of an op-amp circuit will decrease the voltage gain in the same proportion. Thus for a given op amp, the product of gain and bandwidth (i.e., the gain-bandwidth product) is a constant, as discussed earlier and shown in Figure.

Table lists some representative op-amp parameters for different amplifier types, only to illustrate their characteristics. One can see from the table that a high-power op amp can deliver a large output current, but has relatively large offset parameters. On the other hand, a precision input amplifier has low offset and high gain, but at the price of bandwidth, slew rate, and output current. The general-purpose amplifier, as the name suggests, strikes a balance between these extremes.
