RT922 macromodel

3.1

Important note concerning this macromodel

•

All models are a trade-off between accuracy and complexity (i.e. 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, 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 of the specified conditions (for example, VCC,

temperature) or worse, outside of the device operating conditions (for example, VCC, Vicm),

are not reliable in any way.

Section 3.2 provides the electrical characteristics resulting from the use of the RT922,

macromodel.
