CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the
device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
NOTES:
1. θ_JA for the PLCC package is measured with the component mounted on a low effective thermal conductivity test board in free air. See Tech Brief
TB379 for details.
2. θ_JA for the QFN package is measured in free air with the component mounted on a high effective thermal conductivity test board with direct attach
features including conductive thermal vias. θ_JC, the “case temp” is measured at the center of the exposed metal pad on the package underside.
See Tech Brief 379 and AN9922 for additional information and board layout considerations.
