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. Inputs must not go more negative than -0.3V.
2. Short circuits from the output to V+ can cause excessive heating and eventual destruction. The maximum output current independent of V+ is
approximately 20mA.
3.
