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 conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may
affect device reliability.
NOTES:
1. All voltage values, except differential voltages and VCC specified for the measurement of IOS, are with respect to the midpoint
between VCC + and VCC .
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 can be shorted to ground or to either supply. Temperature and/or supply voltages must be limited to ensure that the
dissipation rating is not exceeded.

Input bias currents of a FET-input operational amplifier are normal junction reverse currents, which are temperature sensitive as shown in
Figure 14. Pulse techniques must be used that will maintain the junction temperature as close to the ambient temperature as possible.
