LTSpice - Importing a New Component Model for Simulation

Here's 2 ways I go about importing a SPICE model downloaded from a manufacturer for more accurate simulations if I want to see how a specific part performs.
Using an op amp as an example, we can see how the ideal op amp compares to an LM358 model.
One import method uses the .lib directive to include the model and then just assign it to the existing op amp schematic symbol for the generic op amp.
The other method is to have LTSpice auto-generate a schematic symbol that can be dropped into the schematic if there are no suitable symbols already available. This is useful for unique parts like obscure ICs.

Thank you! I was able to follow along and get it to work with both methods!

Thanks for the video, I'm sure I would never have got the LM358 in LTspice on my own.

Being new to downloading models, I'm trying to find the simple 1 - 2 - 3 steps on how to download a model from a manufacturer. At 2:14 you show that there are models at the manufacturer, then at 2:37 you suddenly have these files in your LTspice folders. I tried the same thing but when I run the simulation LTspice gives me a message, "can't find files". Can you please show HOW to get these files into the correct location instead of saying, "you can download these files"? Yes, we all know that we "can" download these files. We want to know HOW.

I showed that I saved the library files in the same folder as the project files, which should automatically allow it to be found. Apparently LTSpice will also look in a few other locations based off the user home folder as listed here. Maybe you can try putting a library file there and see if it finds it ltwiki.org/LTspiceHelpXVII/LTspiceHelp/html/DotLib.htm
