Derek, will this work? LM321LV data sheet, product information and support | TI.com ( https://www.ti.com/product/LM321LV#design-tools-simulation )

I am trying to work out some old schematic and circuit issues and am looking for a model for the old LM121 opamp. Anyone have such a thing? I found the LM118, as I can use the LTSpice LT118A model.

Great! I look forward to 24.1.6. -- Regards, Tony

Hi Tony, The next update 24.1.6 will support this again. The official syntax for loading table data from a file will be: table(x, .include "<filename>") but yours will also work as is. You will also

Apologies for the mis-steps. Thank you very much for taking the time to explain everything so clearly. I will restore the standard.bjt file and follow your suggestions with regard to the circuit and

So I was right about two different data sources, but both are models, not one model and one measurement results.? The moral of that is, says the Duchess (not of Sussex), is 'Caveat Simulator'.

I wrote: That one, the non-encrypted generic SPICE model, is even older, from 2019 and apparently not updated since.? Who knows what that means. Andy

That is possible, but I think not likely.? By my read, the whole purpose of that Application Note is to show you the results of SPICE simulations.? Therefore, I think none of its plots were from

This is a minor oversight (aka bug) in LTspice. It can't decrypt the file. You can clearly see this from the error messages in the log. Will be fixed in 24.1.6. Meanwhile you can work around it: open

Good point. Pixel pitch, I guess is the more proper term. -- Michael Stokowski LTspice Team Analog Devices Inc.

One more thing to mention here: Because LTspice finds the lack of a load (DC path) connected to node Vout, it "corrects" the omission by adding a small conductance (large resistance) there.? It has

Most modern TVs use algorithms designed to smooth imperfections in the video source material.? They help reduce the appearance of "grain" and similar noise.? Such a smoothing algorithm might

Brady, Here's a better explanation for the difference you saw. Plot the voltage at the top of R1, which is the supply voltage for the fuzz circuit. In the "original" circuit, it stays steady at -9.000

Can you share the command parameters that you used?

Ok I tried it with a normal windows process leveraging the cli (not spicelib) and it works. So the entire problem was passing a .asc instead of a .net file.

It's inside the .ZIP file. Anyway, you don't need it.? Just copy-and-paste one of the two AC128 .MODEL statements in my previous message. Brady had uploaded two schematics and his standard.bjt as

Well, no, I meant 'somehow', because I am not sure that it's possible to actually alter pixel size. -- This email has been checked for viruses by AVG antivirus software. www.avg.com

I can't find the standard.bjt upload.

I think you forgot the :^).? …somewhat smaller. I do like the crosses idea. mike -- Michael Stokowski LTspice Team Analog Devices Inc.
