1.All voltage values, except the differential voltage are with respect to the 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.The 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: a 100 pF capacitor is discharged through a 1.5 kΩ resistor between two pins of the device. This is done for all couples of pin combinations while other pins are floating.

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

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