4 Macromodel
4.1 Important note concerning this macromodel
Please consider the following remarks before using this macromodel.
●All models are a trade-off between accuracy and complexity (i.e. simulation time).
●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 (temperature, supply voltage, for example). 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 4.2 provides the electrical characteristics resulting from the use of this macromodel.
