[sdiy] Spice model for CA3080 OTA

[Pete Hartman]

I'm looking for a CA3080/LM3080 Spice model.  I'm troubleshooting a
few ARP 4023 filters that all seem to exhibit the same basic problems,
AND building it on a breadboard (albeit with slightly different
values/components because of what I have on hand) I get the same
results--no sound.  Not on the output, not on the end of the first
filter stage, nowhere other than the input.  Between the breadboard
and being told that this same PCB has been built and worked, I don't
expect I have a circuit board problem.  I didn't do the builds myself,
BTW.

Next step is to try and look at the filter in LTSpice so I can see a
"working" model, but while I can find .asy and .asc files (from
LTSpice on Yahoo, mostly) I have yet to find something with a subckt
or anything that looks to my (admittedly not very Spice savvy) eye
like a model.  I have tried looking directly at Intersil and TI and
had no more luck there than with google.

If someone has one they can share, that would be great.  If someone
has a suggestion for different simulation software that is 1) not
greatly expensive 2) includes OTA models, and 3) runs on Mac without
too many hoops (LTSpice came in a WINE emulation wrapper, just had to
drop it in place), that would be welcome as well.  I certainly don't
know Spice well enough to be committed to it.

Thanks...
