A diode clamping circuit may be used to limit the output voltage to a particular range. In the diagram, the input signal is not allowed to rise above 0.7 V or to drop below –0.7 V. This circuit is also called a limiter and is typically used to provide protection to a large amplifier such as a high gain op-amp circuit, as shown.
The input clamping op amp architecture of the AD8036 and AD8037 does not operate in the inverting mode. Therefore it is not possible to directly replace an OCA with an ICA for inverting configurations. In order to benefit from the ICA’s superior clamping characteristics in inverting applications, a separate inverting stage is required. Figure 3 shows a circuit with an inverting stage
A clamper circuit is not a clipper, but the simple diode version has a similar topology to a clipper with the exception that the resistor is replaced with a capacitor. The clamper circuit fixes either the positive or negative peaks at a fixed voltage (determined by the biasing voltage) rather than clipping them off.

The use of an op-amp to implement a clamper circuit is where the very high gain of an op-amp is beneficial. The op-amp clamper circuit is shown in fig. 12.

Since the gain of an op-amp is in the millions, the voltage drop is
Frequently the logic being driven by the op amp comparator will not share the op amp’s supplies and the op amp rail to rail swing may go outside the logic supply rails-this will probably damage the logic circuitry, and the resulting short circuit may damage the op amp as well.
