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 sections of this specification is
not implied. Exposure to absolute maximum ratings for extended periods may effect device reliability.
THERMAL CHARACTERISTICS1
Thermal Resistance
28-Lead 300-Mil SOIC
θJA = 55.9°C/W
28-Lead TSSOP
θJA = 67.7°C/W
32-Lead LFCSP
θJA = 32.5°C/W
1 Thermal impedance measurements were taken on a 4-layer board in still air, in accordance with EIA/JESD51-7.
ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the
human body and test equipment and can discharge without detection. Although this product features proprie-
tary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic
discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of
functionality.
