NOTES:

1. Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings

only, and functional operation of the device at these or any other conditions beyond those indicated under “Recommended Operating

Conditions” is not implied. Exposure to absolute maximum rated conditions for extended periods may affect device reliability.

2. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.

3. The maximum package power dissipation is calculated using a junction temperature of 150

°C and a board trace length of 750 mils.
