Hi. I'm trying to use the OPA564 "AC Reference Design" directly as-is from PSPICE. When I place a voltage probe on the output and try to run a simulation, I get errors, including the attached message. What PSPICE modifications are required to run this circuit for AC simulations? Thanks.
Hi John,
We are looking into the issue in PSPICE-FOR-TI tool currently, will get back to you shortly.
BTW, I do not have issues when working with Tina simulator. If you need to simulate a condition, I can help you with that. Please forward me the design requirements, and I can run the tool for you.

Hi John,
Please add voltage probes shown in the image blow, and the issues should be resolved.
Best,
Raymond
Thanks. I tried it. But it brings up this screen. Am I supposed to make parameter adjustments?
Hi John,
This is simulation settings, and you may select OK and resume. I do not see the window popped up after I placed the voltage probes and run the simulation tool.
This is the file that I download from OPA564/OPA564-Q1 (-Q1 refers to automotive grade, which is the same die design as OPA564).

If you are still having issues, I will upload my copy of the reference design.
Also, you should use the latest copy of PSPICE-FOR-TI tool, below is the link.
If you have additional questions, please let me know.
Best,
Raymond
