TINA/Spice/OPA454: OPA454 PSpice model convergence issues in LTSpice.

The PSpice model takes a long time to converge to a DC operating point in LTSpice. Then, even though I do a savebias (operating point) & loadbias, a transient simulation takes a long time to start. Is there an LTSpice-friendly version of this model?

Lance,

We are unable to support our models in LTSpice. Have you tried the same model in TINA-TI (www.ti.com/.../toolssoftware) I t is a free simulator from TI and if you are new to it there is a short video training series that you will find very helpful to ramp up on the tool: training.ti.com/tina-ti-video-training-series

Thanks, I'll give it a try & get back to you. However, it's more work if I have to regenerate my circuits in another tool because of one model.
