2. Differentialvoltages are at the non-inverting inputterminalwith respect tothe inverting inputterminal.

3. The magnitude of theinputvoltage mustnever exceed themagnitude ofthe supply voltage or 15 volts,whichever is less.

4. The output may be shorted to ground or to eithersupply.Temperature and /orsupply voltages mustbe limitedto ensure thatthe
