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_CC⁺and V_CC

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 with respect to the inverting input terminal.

4. Short-circuits can cause excessive heating. Destructive dissipation can result from simultaneous short-circuits on all

amplifiers.

5. Rth are typical values.

6. 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.

7. Human body model: 100pF discharged through a 1.5kΩ resistor between two pins of the device, done for all couples of pin

combinations with other pins floating.

8. Machine model: a 200pF cap is charged to the specified voltage, then discharged directly between two pins of the device

with no external series resistor (internal resistor < 5Ω), done for all couples of pin combinations with other pins floating.

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

the ground.
