LTspice. LTspice ® is a high performance SPICE simulation software, schematic capture and waveform viewer with enhancements and models for easing the simulation of analog circuits. Included in the download of LTspice are macromodels for a majority of Analog Devices switching regulators, amplifiers, as well as a library of devices for general. Model files can often be downloaded by vendor sites, but LTSpice only comes pre-loaded with models of common LT components. ## Step 1: Download a Model (.mod) File I found [`LM741.MOD`](LM741.MOD) available on the TI's [LM741 product page](https://www.ti.com/product/LM741). Save it wherever you want, but you will need to know the full path to this file later. ## Step 2: Determine the Name Open the model file in a text editor and look for the line starting with `.SUBCKT`. The top of LM741.MOD.
