Notes : 1. All voltage values, exceptdifferential voltage,are with respect to thezero reference level (ground) of the supply voltages where the
zero reference level is the midpoint between VCC+andVCC–.
2. Differentialvoltages are at the non-inverting inputterminal with respect to the inverting input terminal.
3. The magnitude of the input voltage must never exceed the magnitude of the supply voltageor 15 volts, whichever is less.
4. The output may be shorted to groundor to either supply. Temperature and /orsupply voltages must be limitedto ensure that the
dissipation rating is not exceeded.
