Notes:

Table 2: Operating conditions

⁽¹⁾All voltage values, except the 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- .

⁽²⁾The magnitude of the input voltage must never exceed the magnitude of the supply voltage or 15 volts, whichever is less.

⁽³⁾Differential voltages are the non-inverting input terminal voltages with respect to the inverting input terminal.

⁽⁴⁾Short-circuits can cause excessive heating. Destructive dissipation can result from simultaneous shortcircuits on all amplifiers.

⁽⁵⁾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.

⁽⁶⁾Human body model: 100 pF discharged through a 1.5 kΩ resistor between two pins of the device. This is done for all couples of pin combinations with other pins floating.

⁽⁷⁾Machine model: a 200 pF cap is charged to the specified voltage, then discharged directly between two pins of the device with no external series resistor (internal resistor < 5 W). This is done for all couples of pin combinations with other pins floating.

⁽⁸⁾Charged device model: all pins plus package are charged together to the specified voltage and then discharged directly to the ground.
