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. _JA is measured with the component mounted on an evaluation PC board in free air. See Tech Brief TB379.
Electrical Specifications AV_DD = DV_DD = +3.3V, V_REF = Internal 1.2V, IOUTFS = 20mA, T_A = +25°C for all typical values. Boldface limits
apply across the operating temperature range, -40°C to +85°C.
