†

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and

functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not

implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTES: 1. All voltage values, unless otherwise noted, are with respect to the midpoint between V

CC+

and V

CC–

2. Differential voltages are at IN+ with respect to IN–.

3. The magnitude of the input voltage must never exceed the magnitude of the supply voltage or ±15 V, whichever is less.

4. The output may be shorted to ground or either power supply.
