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 VCCand VCC. 2. Differential voltages are at the non-inverting input terminal with respect to the inverting input terminal. 3. The magnitude of the input voltage must never exceed the magnitude of the supply voltage or 15 volts, whichever is less. 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.
