Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime. 2. A heat sink may be required to keep the junction temperature below the absolute maximum rating when the output is shorted indefinitely. 3. Thermal resistance varies with the amount of PC board metal connected to the package. The specified values are for short traces connected to the leads. 4. Full power bandwidth is calculated from the slew rate FPBW = SR/(π • VP-P).
