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 with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief
TB379 for details.
5. For θ_JC the “case temp” location is the center on the top of package.
Analog Specifications Over recommended operating conditions unless otherwise stated. Boldface limits apply over
the operating temperature range, -40°C to +125°C.
