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 V CC and V CC. 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 noninverting 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 2/
