OPA2134 SPICE model

[Helix]

I am looking for a OPA2134 spice model to use in Or_cad PSPICE.
Does anyone have it or can suggest a near equivilent model?

There's a SPICE model on the TI site.

I've not tried it but TI models are usually OK.

oh yeah, thanks...

seems obvious now

I got the subcircuit right, but which .asy to use?
Can someone suggest me a similar opamp scheme from ltspice library to use?

Go the LTSpice's symbol library and put opamp2 on the schematic. Paste the contents of OPA2134.LIB onto the schematic, then name the opamp OPA2134. I do this usually since it's the fastest way to get a simulation running.

Here is one they I've set up. Just unzip into the folder you have your main asy file in and include the opa134.sub with a .include I find that much cleaner than adding into the lib dir and the asy directory. It also makes it easy to zip up an entire working model.

I am getting an error message when I try to run a simulation where it's used.
I get: "Unknown subcircuit called in: xu3 0 n002 +12 -12 n004 opa134"
(copied the .sub into ltspiceIV/lib/sub/ and asy into ltspiceIV/lib/sym/opamps)

Me too, just not xu3 but xu1

probably some things are different in the recent LTspice version.
Please, can somebody help to solve this issue?

Hmm, I'll see if I can check tonight. I don't have the new spice on my laptop or main computer, but I did install it on my duaghers laptop earlier in the year. I can't remember what I was simulating at the time but I think it was one of my existing circuits, and I don't remember having to do anything to get it working...

Actually I could have been clearer with the post with the attached zip file.

I actually create a separate directory for each project I work on. It is in that directory that I put the .sub and .asy files. I do not add them to the system library paths.

When you go to add the component you click on the little drop down for the component location and select the directory which you are in. The models then show up so you can pick them. Screen shot shows different models available in my synergy directory.

One of the benefits of doing it this way is that the project is completely portable and will just work on a completely vanilla install of ltSpice (at least ltspice IV)

Thanks!

I don't think that location of the files is the issue.
I have the opa134.asy and opa134.sub in the correct folders together with other models which I downloaded and they work fine, except for this one...
