Differential Input Voltage - note
°C °C
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 -. The magnitude of the input voltage must never exceed the magnitude of the supply voltage or 15 volts, whichever is less. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal. 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
