1.All voltage values, except differential voltage, are with respect to network ground terminal.

2.Differential voltages are the non-inverting input terminal with respect to the inverting input terminal.

3.VCC-Vin must not exceed 6 V, Vin must not exceed 6 V.

4.Input current must be limited by a resistor in series with the inputs.

5.VCC-Vshdn must not exceed 6 V, Vin must not exceed 6 V.

6.Short-circuits can cause excessive heating and destructive dissipation.

7.Rth are typical values.

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

9.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 Ω), done for all couples of pin combinations with other pins floating.

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