LTspice wurde von Mike Engelhardt entwickelt und gehört inzwischen zu Analog Devices. Es handelt sich dabei um ein Programm zur Schaltplanerstellung - einen leistungsstarken, schnellen und kostenlosen SPICE-Simulator sowie um ein Werkzeug zur Darstellung von Kurvenverläufen. Es bietet eine umfangreiche Bauteildatenbank, die weltweit durch SPICE-Modelle unterstützt wird.Mit LTspice kann man schnell und einfach Schaltpläne erstellen. Dank der leistungsfähigen grafischen Ausgabefunktionen lassen sich Spannungen und Ströme in einer Schaltung, die Leistungsaufnahme der Bauteile und viele weitere Parameter darstellen.Ziel dieses Buches ist es, den Entwurf und die Simulation elektronischer Schaltungen mit LTspice zu vermitteln. Es behandelt unter anderem folgende Themen:- DC und AC-Schaltungen- Kleinsignal- und Z-Dioden- Transistorschaltungen inkl. Oszillatoren- Tryristor-, Diac- und Triacschaltungen- Operationsverstärkerschaltungen inkl. Oszillatoren- Der 555 Timer-IC- Filter- Spannungsregler- Optokoppler- Erstellung von Spannungskurven- Simulation von Logikschaltungen mit der 74HC-Familie- SPICE-Modellierung LTspice ist ein äußerst vielseitiges Werkzeug zur Simulation elektronischer Schaltungen mit zahlreichen Funktionen und Anwendungsmöglichkeiten. Eine vollständige Behandlung aller Details würde jedoch den Rahmen dieses Buches sprengen. Daher konzentriert sich das Buch auf die gängigsten Themen wie DC- und AC-Analyse, Parametersweep, Übertragungsfunktionen, Oszillatoren, Diagramme und weitere grundlegende Anwendungen.Obwohl es sich um eine Einführung handelt, deckt dieses Buch dennoch die meisten Interessensgebiete all jener ab, die sich mit der Simulation elektronischer Schaltungen beschäftigen.
