CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operationof the

device at these or any other conditions above those indicated in the operational sections of this specification is not implied.

NOTES:

1. Long term offset voltage stability will be degraded if large input differential voltages are applied for long periods of time.

2. The outputs may be shorted to ground or to either supply, for VSUPPLY ≤10V. Care must be taken to insure that the dissipation rating is not

exceeded.

θJA is measured with the component mounted on an evaluation PC board in free air.
