NOTES:
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.
5.
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
6. For
θJC, the “case temp” location is the center of the exposed metal pad on the package underside.
7. For
θJC, the “case temp” location is taken at the package top center.
Analog Specifications
VCC = 2.7V to 5.5V, VLOGIC = 1.2V to 5.5V over recommended operating conditions unless otherwise
stated. Boldface limits apply over the operating temperature range, -40°C to +125°C.
