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:

θJA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.

5. For

θJC, the “case temp” location is taken at the package top center.

Electrical Specifications VREF = VDD V, VDD = 2.7V to 5V, VCM=VDD/2,SCLK=20MHzandTA=-40°Cto+125°C(typicalperformance

at +25°C), unless otherwise specified. Boldface limits apply over the operating temperature range, -40°C to +125°C.
