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. Absolute maximum ratings are limiting values, applied individually, beyond which the serviceability of the circuit may be impaired. Functional
operability under any of these conditions is not necessarily implied.
2.
θ
JA
is measured with the component mounted on an evaluation PC board in free air.
3.
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. See Tech Brief TB379 and TB389 for additional information and board layout consideration
