Absolute Maximum Ratings

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be opera-

ble above the recommended operating conditions and stressing the parts to these levels is not recommended. In addi-

tion, extended exposure to stresses above the recommended operating conditions may affect device reliability. The

absolute maximum ratings are stress ratings only. Absolute maximum ratings apply individually only, not in combina-

tion. Unless otherwise specified, all other voltages are referenced to AGND.

Notes:

1. Junction-to-ambient thermal resistance, θJA, is a strong function of PCB material, board thickness, thickness and

number of copper planes, number of vias used, diameter of vias used, available copper surface, and attached heat

sink characteristics.
