2. Differentialvoltages areat the non-inverting input terminalwithrespect totheinverting input terminal.

3. The magnitude of the inputvoltage mustnever exceed the magnitude of the supply voltageor 15 volts, whicheveris 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.
