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 > ±1V, the maximum input current must not exceed ±1mA. In this case (Vid > ±1V) an input serie resistor must be added to limit input current. 3. Human body model, 100pF discharged through a 1.5kΩ resistor into pin of device. 4. Machine model ESD, a 200pF cap is charged to the specified voltage, then discharged directly into the IC with no external series resistor (internal resistor < 5Ω), into pin to pin of device. 5. 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 80mA, independent of the magnitude of Vcc. Destructive dissipation can result from simultaneous short-circuits on all amplifiers. Table 2.

Macromodels are not a substitute to breadboarding; rather, they confirm the validity of a design approach and help to select surrounding component values. A macromodel emulates the NOMINAL performance of a TYPICAL device within SPECIFIED OPERATING CONDITIONS (i.e. temperature, supply voltage, etc.). Thus the macromodel is often not as exhaustive as the datasheet, its goal is to illustrate the main parameters of the product. Data issued from macromodels used outside of its specified conditions (Vcc, Temperature, etc) or even worse: outside of the device operating conditions (Vcc, Vicm, etc) are not reliable in any way. ● In Section 3.3, the electrical characteristics resulting from the use of these macromodels are presented. 3.2 Electrical characteristics from macromodelization Table 5.
