Notes : 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 V andV
CC CC .
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.
