content: I have searched google for "ltspice library download," "LTSpice third party library," etc. Maybe I'm using bad terminology here.It seems to me like someone would share a comprehensive library of the basics like the classic dip based op amps, diodes, transistors, and typical Radio Shack basics. Anyone know some good references or at least point me in the right direction?

content: You might be able to get a discounted version of TINA (TI's simulator)Or, you could check in with the VERY knowledgeable folks on the LTSpice forum at groups.yahoo.com Their are actually 2 groups: One for discussions and files in transit and another that serves as a place holder for more permanent files (models).You can't seriously expect Linear Technology to spend a bunch of money modeling parts from other manufacturers. Most of the other manufacturers offer spice models of their devices and these can be modified to work with LTspice.You can also take the existing diode models and change the various parameters to create your own model. Assuming the diode manufacturer provides the parameters.

content: There are already quite a few parts included. OPs are limited to the LT parts for obvious reasons, but in many cases one can just look up an similar LT part for the simulation or use the universal OP and adjust the parameters on that. Other part can be included but they take some work.

content: Also, if you share your circuits, and have installed third party libraries, it is *VERY* difficult to keep track of which parts are 'vanilla' LTSPICE and which are 3rd party. You then have the situation that no-one else can simulate your circuits until you tell them which extra libraries they need to install, or even worse, symbols are missing from the schematic.If instead you put the 3rd party models and symbols in the same subfolder as the schematic, you can zip it up (pruning generated files) and share it in the knowledge that it will run on any recipient's LTSPICE. Unfortunately the discrete component browser only works on the lib\cmp\standard.* model files and LTSPICE's update process tends to strip comments and rearrange the component files' contents, so you cant simply add your third party libraries pick a model from the component browser lists and distinguish which ones need to be copied to the schematic folder so it can be a PITA creating portable LTSPICE schematics, as each model name (part num.) must be entered manually.

content: There are loads of third-party models on the web, you just have to pick through them and cut-&-paste what you want into your own files.Try searching for "standard.dio", "standard.bjt" etc or "spice .model"Depending on source, you'll find that the parameter list may vary slightly for the same part, but for "jellybean" parts that probably doesn't matter too much.A couple of tips:As you compile your own library of parts, be sure to keep a backup copy out of the LTspice directory. When you update the software it tends to overwrite the files.Place the .model syntax for your chosen jellybean parts at the top of the standard.dio/bjt/whatever file. That way they show at the top of the list when you need to select them.
