Simple Output-limiter Circuit Diagram HA-5190 is rated for ±5 V output swing, and saturates at ±7 V.
As with most op amps, recovery from output saturation is slow compared
to the amplifier`s normal response time. Some form of limiting, either
of the input signal or in the feedback path, is desirable if
saturation might occur. The circuit illustrates a feedback limiter, where gain is reduced
ifthe output exceeds ± ( Vz + 21j-). A 5-V zener with a sharp knee
characteristic is recommended.
