Stresses above those listed under Absolute Maximum Ratings

may cause permanent damage to the device. This is a stress

rating only; 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.

THERMAL RESISTANCE

The exposed pad (EPAD) must be soldered to the ground plane

(AVSS) for the 72-lead LFCSP. The EPAD provides an electrical,

thermal, and mechanical connection to the board.

Typical θJA, θJB, and θJC values are specified for a 4-layer board in

still air. Airflow increases heat dissipation, effectively reducing

θJA and θJB.
