Exposure to such conditions may adversely impact product reliability and result in failures not covered by warranty. NOTES: 1. θ 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. θJA 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. 3. For θ JC, the “case temp” location is the center of the exposed metal pad on the package underside. 4. 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.
