For more information about traditional and new thermal metrics, see the IC Package Thermal Metrics application report, SPRA953.
The maximum power dissipation is a function of TJ(MAX), RθJA, and TA. The maximum allowable power dissipation at any ambient temperature is PD = (TJ(MAX) – TA)/ RθJA . All numbers apply for packages soldered directly onto a PC board.

Absolute maximum ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is intended to be functional, but specific performance is not ensured. For ensured specifications and the test conditions, see the Electrical Characteristics.
Applies to both single-supply and split-supply operation. Continuous short circuit operation at elevated ambient temperature can result in exceeding the maximum allowed junction temperature of 150°C.
Typical Values represent the most likely parametric norm.
All limits are specified by testing or statistical analysis.
Average drift is determined by dividing the change in parameter at temperature extremes into the total temperature change.
Slew rate is the slowest of the rising and falling slew rates.
Simulation results.
Short circuit test is a momentary test. Output short circuit duration is 1.5 ms.
Electrical table values apply only for factory testing conditions at the temperature indicated. Factory testing conditions result in very limited self-heating of the device such that TJ = TA. No ensured specification of parametric performance is indicated in the electrical tables under conditions of internal self-heating where TJ > TA. Absolute maximum ratings indicate junction temperature limits beyond which the device may be permanently degraded, either mechanically or electrically.
