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. Values apply for each section of the dual amplifiers.
2. All types in any package style can be operated over the temperature range of -55oC to 125oC, although the published limits for certain electrical
specification apply only over the temperature range of 0oC to 70oC.
3. θJA is measured with the component mounted on an evaluation PC board in free air.
