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:
1. _JA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
2. For _JC, the “case temp” location is the center of the exposed metal pad on the package underside.
3. Jedec Class II pulse conditions and failure criterion used. Level B exceptions are: using a max positive pulse of 6.5V on the SHDN pin, and using
a max negative pulse of -0.8V for all pins.
Analog Specifications Over recommended operating conditions, unless otherwise stated.
