7.3.13 Overload Recovery

Overload recovery is defined as the time required for the op amp output to recover from a saturated state to a linear state. The output devices of the op amp enter the saturation region when the output voltage exceeds the rated operating voltage that results from the high input voltage or the high gain. After the device enters the saturation region, the charge carriers in the output devices must have time to return back to the normal state. After the charge carriers return back to the equilibrium state, the device begins to slew at the normal slew rate. As a result, 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 OPAx828 is approximately 55 ns.
