It's been asked quite a few times how to import PSpice models into LTspice but none of the methods seem to apply to this particular model from TI. I really don't understand what all these files are inside the .zip. Isn't there supposed to be a .lib file somewhere which we can link to a component?

Here is a model for the OPA313 if you follow the link and scroll down a bit.

Under sbomaq3b\opa313-PSpiceFiles\SCHEMATIC1\transient there is a .cir file which my computer seems to think is an LTspice netlist file. Opening it in LTspice gives me this:

The model is in the root directory of the archive. Use opa313.lib.

  • \$\begingroup\$ This worked. Thank you. For some reason my windows computer does not recognize that as a .lib file. After opening it in LTspice now, it's identifying it as a an altium library file. Very interesting. I also followed these steps: analog.com/en/technical-articles/… \$\endgroup\$

  • \$\begingroup\$ @BobaJFET You shouldn't assume only files which claim an association with LTspice are the only ones that can be used within LTspice. For example, SPICE models from OnSemi might have a .SP3 extension which will work in LTspice. If the manufacturer ships a bunch of different files, of course try opening the .LIB first using the method in step 1 of the article you linked. If that's not it, start trying others until you file a .MODEL or .SUBCKT statement near the top of the text. Also, if you haven't already you should tell your Windows OS to always show file extensions. \$\endgroup\$
