Absolute Maximum Ratings

Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All

voltage parameters are absolute voltages referenced to COM. The thermal resistance and power dissipation

ratings are measured under boardmounted and still air conditions.

All supplies are fully tested at 25 V. An internal 20 V clamp exists for each supply.

Recommended Operating Conditions

For proper operation, the device should be used within the recommended conditions. All voltage parameters

are absolute voltages referenced to COM. The offset rating are tested with supplies of (VCC-COM)= (VB-

VS)=15 V.
