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:
4. θJA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief
TB379 for details.
Electrical Specifications VDD = 3.6V. Typical Values Are Tested at VDD = 3.6V and the Ambient Temperature
at +25°C. All Maximum and Minimum Values Are Established Under the Recommended
Operating Supply Voltage Range and Ambient Temperature, Unless Otherwise
Noted.
