Important note concerning this macromodel

Please consider 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 (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.

reliable in any way.
