4 Macromodel
4.1 Important note concerning this macromodel
Please not the following points before using this macromodel
• All models are a trade-off between accuracy and complexity (that is, simulation time)
• Macromodels are not a substitute for 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 (for example, temperature and supply voltage). 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 the specified conditions (for example, V
CC
and temperature) or even worse, outside of the device’s operating conditions (for example,
V
CC
and Vicm), are not reliable in any way.
