Overload recovery is defined as the time required for the operational amplifier output to recover from a saturated state to a linear state. The output stage of the operational amplifier enters a saturation region when the output voltage exceeds the rated operating voltage, because of the high input voltage or high gain. After one of the outputs enters the saturation region, the output stage requires additional time to return to the linear operating state which is referred to as overload recovery time. After the output stage returns to linear operating state, the amplifier begins to slew at the specified slew rate. Therefore, the propagation delay (in case of an overload condition) is the sum of the overload recovery time and the slew time.

The overload recovery time for the OPAx323 family is designed to be approximately 130ns typical.
