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:
4. θ_JA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features. See
Tech Brief TB379.
5. For θ_JC, the “case temp” location is the center of the exposed metal pad on the package underside.
6. Jedec Class II pulse conditions and failure criterion used. Level B exceptions is using a minimum negative pulse of -0.8V on the A1 pin.
Analog Specifications Over recommended operating conditions unless otherwise stated.
