LMC6484: LMC6484 Spice Model

Hello Todd,

I have attached the text SPICE model to this message which was just updated and is valid for the entire LMC648x family. This new model is in the process of getting uploaded to the web and will soon appear in the "Tools and software" tab of the LMC6484 product page.

LMC6482.LIB

Hi Ian,

Thanks for prompt reply to my request. Unfortunately, the model you had provided does not appear to work with ngspice (used with Cygwin). This is peculiar, as the NI spice model library (which includes LMC6484) works fine. Any ideas? If it's nothing obvious to you, I'll dig in further on the resulting ngspice run errors and report back.

Best Regards,
Todd

Hello Todd,

This is my first time hearing of Ngspice or Cygwin, but our SPICE model architecture is tested and compatible with all PSpice-based simulators. Let me know what run errors you're observing and we can go from there.

Best regards,

We haven't heard back from you so we assume you were able to resolve your issue. If not, post another reply below.

Thanks

I was not looking for a PSPICE model. I was looking for a spice text model.

Hi Dennis,

Sorry - I haven't had a chance to work on this problem for a while.  So you're saying Ian's attachment was a spice model - I was under the impression it was pspice,? I thought that was the reason it wouldn't run in ngspice.  I'll run the deck in ngspice, and send the results. 

Best Regards,

Todd
