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 4.2, the electrical characteristics resulting from the use of this macromodel are presented. 4.2 Electrical characteristics from macromodelization Table 4.
