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.
θJA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
7. For
θJC, the “case temp” location is taken at the package top center.
Electrical Specifications VDD = +3.0V to +3.6V, fSCLK = 18MHz, fS = 1MSPS, VREF = 2.0V; VDD = +4.75V to +5.25V, fSCLK =18MHz,
fS =1MSPS, VREF = 2.5V; VCM = VREF, unless otherwise noted. Typical values are at TA = +25°C. Boldface limits apply over the operating temperature
range, -40°C to +85°C.
