Is it possible to upload your schematic to the forum? There are several community members familiar with op-amps who may be able to assist. This will also help the community gain a better understanding of why Qspice sometimes encounters difficulties when running TI models. @OHara recently conducted an in-depth review of a TI model, narrowing down the issue to how the switch behaves, and this information has been forwarded to Mike for review.

If you have confidential information in your schematic, please consider whether you can reduce the simulation to a level that can be shared while still retaining the problem.
