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.
NOTE:
3. θJA is measured with the component mounted on a low effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
Electrical Specifications
AVDD = DVDD = +5V (unless otherwise noted), VREF = Internal 1.2V, IOUTFS = 20mA, TA = -40°C to +85°C for
all Min and Max Values. TA = +25°C for All Typical Values. Boldface limits apply over the operating
temperature range, -40°C to +85°C.
