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. If Vid > ±1 V, the maximum input current must not exceed ±1 mA. In this case (Vid > ±1 V), an input series resistor must be added to limit input current. 3. Do not exceed 14 V. 4. Short-circuits can cause excessive heating and destructive dissipation. Rth are typical values. 5. Human body model: A 100 pF capacitor is charged to the specified voltage, then discharged through a 1.5 kΩ resistor between two pins of the device. This is done for all couples of connected pin combinations while the other pins are floating. 6. 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 connected pin combinations while the other pins are floating. 7. Charged device model: all pins and the package are charged together to the specified voltage and then discharged directly to the ground through only one pin. This is done for all pins. 8. There is no short-circuit protection inside the device: short-circuits from the output to VCC can cause excessive heating. The maximum output current is approximately 80 mA, independent of the magnitude of VCC. Destructive dissipation can result from simultaneous short-circuits on all amplifiers. Table 2.

Thus the macromodel is often not as exhaustive as the datasheet, its purpose is to illustrate the main parameters of the product. Data derived from macromodels used outside of the specified conditions (VCC, temperature, for example) or even worse, outside of the device operating conditions (VCC, Vicm, for example), is not reliable in any way. Section 3.2 presents the electrical characteristics resulting from the use of these macromodels. 3.2 Electrical characteristics from macromodelization Table 5.
