=====My LTSpice Components===== [[http://www.linear.com/designtools/software/|LTSpice]] is an excellent SPICE circuit simulator available free of charge from LTC. However, I some parts that I like to use are not included as standard components. The purpose of this page is to provide download links to LTSpice models these parts to save myself the future effort of searching for them. The ''.sub'', ''.lib'', or ''.mod'' file goes in the LTSpice/lib/sub directory, the ''.asy'' files go in the LTSpice/lib/sym directory (or a subdirectory such as ''opamps'', if appropriate): * [[http://www.femm.info/Archives/contrib/ltspice/shuntregulators.zip|TL431 and TLV431]] shunt regulators. * [[http://www.femm.info/Archives/contrib/ltspice/LM339.zip|LM339]] quad comparator. * [[http://www.femm.info/Archives/contrib/ltspice/LM324.zip|LM324]] quad op amp. * [[http://www.femm.info/Archives/contrib/ltspice/TL082.zip|TL082]] wide bandwidth dual JFET opamp.
