Notes:
1. Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating
only and functional operation of the device at these or any other conditions above those indicated in the operational section of this
specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
Absolute maximum ratings apply individually only, not in combination. Unless otherwise specified all other voltages are referenced
to GND.
2. Junction to ambient thermal resistance, θ_JA, is a strong function of PCB material, board thickness, thickness and number of copper
planes, number of via used, diameter of via used, available copper surface, and attached heat sink characteristics. Measured with
the device mounted on a board of FR-4 material, 0.063” thickness, no copper plane and zero airflow.
