Macromodels
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.
– Data issued from macromodels used outside of its specified conditions (V
CC
,
Temperature, etc.) or even worse: outside of the device operating conditions (V
CC
,
V
icm
, etc.) are not reliable in any way.
In
the electrical characteristics resulting from the use of this macromodel are
presented.
