Note 1. All voltage values, except differential voltages, are with respect to the midpoint between
V
CC
+ and V
CC
–.
Note 2. Differential voltages are at the non–inverting input pin with respect to the inverting input pin.
Note 3. The magnitude of the input voltage must never exceed the magnitude of the supply voltage
or 15V, whchever is less.
Note 4. The output may be shorted to GND or to either supply. Temperature and/or supply voltages
must be limited to ensure that the dissipation rating is not exceeded.
