TINA/Spice/OPA2132: Convergence Problem

jpe27,

Could you provide the .TSC file that is giving you the issues?

TINA-TI has an example circuit for the OPA2132 in the Open Examples...TI Test Circuits directory. You could check the simulation parameters there for any guidance.

I would also note that the TINA-TI model is not encrypted and does not have any temperature dependence built into the model.

thanks very much for your reply.
I took the suggestion of using the OPA132 test circuit and using the simulation analysis parameters and now my circuit converges and runs.

However, if the model of the OP Amp has no temperature dependence, what is the best way of evaluating device performance in TINA TI over a temperature range? I can view the spice macro but I am not familiar with which parameters to vary or the limits. I assume these devices are generated from measurements data, or else the IC design?
 
I can enter temperature dependent characteristics for other components, but if the model does not vary with temperature then the simulation is not truly accurate. I mean I can only model the variation in performance using the external circuit components and not evaluate the amplifier variation as well.

Thanks in advance.

Hello Britt

any further response to this?

Thanks in advance.
