Hallo, ich habe mir auf der Homepage von TI das PSpice-Model für den LM1875 gedownloadet. Folgender Fehler wird vier mal nacheinander beim Simulationsversuch in LT-SPice ausgegeben: Warning: Can't resolve .param ibrkv=1m Hier das Modell (so habe ich es auch in LT-Spice eingebunden): * LM1875 ************************************************************************ ***** * (C) Copyright 2012 Texas Instruments Incorporated.
