CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product

reliability and result in failures not covered by warranty.

NOTES:

6. Voltage Ratings are all with respect to the AGND pin.

7. JA is measured in free air with the component mounted on a high-effective thermal conductivity test board with “direct attach” features. See TB379.

8. For JC, the “case temp” location is the center of the exposed metal pad on the package underside.

9. PSIJT is the PSI junction-to-top thermal characterization parameter. If the package top temperature can be measured with this rating then the die

junction temperature can be estimated more accurately than the JC and JC thermal resistance ratings.

10. PSIJB is the PSI junction-to-board thermal characterization parameter.

Electrical Specifications VIN = EN = 3.3V, TA = +25°C unless otherwise noted. Boldface limits apply over the operating temperature

range, -40°C to +85°C.
