1. All voltage values, except differential voltage, are with respect to the zero reference level (ground) of the supply voltages where the zero reference

level is the midpoint between VCC+ and VCC-.

2. The magnitude of the input voltage must never exceed the magnitude of the supply voltage or 15 volts, whichever is less.

3. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal.

4. The output may 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
