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.

example), is not reliable in any way.
