7.3.5 Thermal Shutdown

If the die temperature exceeds safe limits, all outputs are disabled, and the OTF/SH_DN pin is driven low. After the die temperature has fallen to a safe level, operation automatically resumes. The OTF/SH_DN pin is released after operation has resumed.

When operating the die at a high temperature, the op amp toggles on and off between the thermal shutdown hysteresis. In this event, the safe limits for the die temperature must be taken in to account; see the Recommended Operating Conditions and Thermal Conditions tables. Do not continuously operate the device in thermal hysteresis for long periods of time; see the Recommended Operating Conditions table.
