Macromodels

Note:

Note: 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.

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.
