Hello,

I am getting "Element type mismatch" error when trying to simulate LMV881 driving capacitive load.

Simulation circuit works with other op amps.

Is there a problem with the model?

Thank you,

GMC,

Would you please upload your TINA schematic file (*.TSC) to this thread so we can see the problem.

Regards,
John

GMC,
The netlist text header says the model was made to be used in NGspice.
I went ahead and tried to use the model in Pspice (TINA is Pspice-compatible) and the model did indeed fail.
The NGspice syntax it uses is not compatible with Pspice and TINA.

The only suggestion I can make at this point is to try to get a copy of NGspice and try to run your sims in that tool.
Regards,
John
