Hello,
I am following this video,
https://training.ti.com/ti-precision-labs-adcs-selecting-and-verifying-d...
and I would like to plot the open loop gain as Texas did. Texas TI uses the Tina TI simulator but I would like to use the PSpice TI. The first time I tried to simulate it complained about the source V4 suggesting that I needed to add a resistor, R4. After that, the AC Sweep analysis takes a lot of time and fails to complete the simulation.

Best regards,
EDIT: Is it possible to read directly (or through some math calculations) the Open Loop Output Impedance from the PSpice model of OPA340?

I set up a simple single ended voltage follower using the OPA340. I then ran a bias point analysis and experienced the same long analysis time as you did so I cancelled out early. I added a negative voltage source to VEE and ran the bias point again. This time it completed the calculations in a very reasonable amount of time. Something isn't right with that model.
Thank you retiredEE,
I will just contact Texas Instruments to try to solve the problem.
Best regards,
