Hello Di,
Convergence issues with Pspice simulators are not all that uncommon. It might be something with the way you arranged your Pspice circuit, or something about a simulation model design that results in convergence difficulties.
If you are using Cadence/Orcad Pspice there is a blog about using the AutoConvergence feature which may help you get past the convergence problems. You can find the blog here:
Just for a reality check I ran our OPA180 simulation model using the TopSPICE simulator software and didn't encounter even the slightest convergence issue. TopSPICE is syntax compatible with Cadence Pspice. Shown below is an example of a transient analysis performed using the OPA180 simulation model.
If you continue to have convergence problems, you can send us an image of your Ppsice circuit design and we can look it over.
