Note: 1. Includes all power generated by AC and/or DC output loading.
2. The power supply pins are at maximum values listed in “Recommended Operating Conditions”, below.
3. At ambient temperatures above 70° C, total power dissipation must be limited to less than 2.5 Watts.
WARNING: Operation beyond these limits may result in permanent damage to the device.
Normal operation is not guaranteed at these extremes.
