ADS7851: Pspice model

Hi Ryan,

Thank you for the response. 

The customer tried to open the .TSC file in TINA and export a *.CIR file there is the line "* SUBCKT: ADSXX51_SCH_0 encrypted macro, content not displayed". So they can't generate a part in PSPICE.

Can you help further? 

Regards,

Marvin

Hello Marvin,

Let me discuss with the team how to best support this. We may have to convert the model to PSPICE ourselves and release it separately. I'll get back to you shortly.

Regards,

Ryan

Hi Ryan,

Any update on this? Have you converted the model to PSPICE? Would you kindly share the link or the file?

Thanks!

Marvin

Hi Marvin,

Thanks for your patience. I don't have a converted model just yet. We are working to find resources to do it, but I've notified the right people to this request and expect a response shortly.

Ryan

Hi Ryan. 

Thank you very much. I will wait for your response.

Hello Marvin,

I've learned that it's the device netlist itself which is encrypted. We would need an unencrypted netlist in order to port the model to PSpice. I'm still working to see if it will be possible to support this request.

Ryan

Hi Ryan,

Thank you. Please let me know if you are able to support this request.

Hi Marvin - this will not be an easy request to support. We are meeting about this again tomorrow, but it will take some time to develop the model.

Ryan

Hi Ryan,

Thanks for the update. Please let me know if you are able to develop a model.

Hi Marvin,

We are working to develop a model in PSpice by the end of this week. I'll review it once completed and then let you know when it's available for download.

Hi Ryan,

Thank you so much for the help. I am looking forward to this.

Marvin,

Please refer to :  https://www.ti.com/lit/an/sbaa531/sbaa531.pdf for details on how to use the mode and how it functions.  I can help answer questions as well.

Hi Art,

Thank you for the reference document.

I would like to know if were you able to develop a model in PSpice as Ryan previously suggested?

Thank you.

Regards,

Marvin

Marvin,

Yes.  It is in the library.  To access the TI library you can select "Place>PSpice Component > Search".  Then find the ADC folder and past the part.  You can also download the reference design from the device folder on TI.com and unzip it.  The document that I linked in gives a lot of detail on how to use the model and what kind of simulations are useful.
