macromodel ts912, ts912a, ts912b 12/20 doc id 2325 rev 6 4 macromodel 4.1 important note concerning this macromodel all models are a trade-off between accuracy and complexity (i.e. simulation time). macromodels are not a substitute 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 ex haustive as the datasheet, it s purpose is to illustrate the main parameters of the product. data derived from macromodels used ou tside of the specified conditions (v cc , temperature, for example) or even worse, outside of the device operating conditions (v cc , v icm , for example), is not reliable in any way. figure 14. input voltage noise vs. frequency + ++ + + + ++ +++ ++++ 91': '#)2;* ,+ ,- $ / ,++ 1 ': %"'$! $ "$%&'') .2;*
