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. Input voltages may exceed the supply voltages provided the input current is limited to
±100µA.
2. TEST pin is connected to internally generated digital ground through a 500Ω resistor (see text for TEST pin description).
3.
