TMS320F28377D: Quality & Reliability/Environm

Dear team:

I am developing my doctoral project with the TMDXDOCK28377D - Soprano F28377d Experimenter Kit that I bought at 07 december 2015.
I am having various problems with the ADC sampling.
When I searched for these problems, I noticed that the silicon revison (B) of my control card under-estimates the value of the sampling switch resistance (Ron) according to sprz412i. I tried many of the suggestions of the forum community and the sprz412i, but I can't get quite results.
The F28335 works very well, and I never had any problems with any signal conditioning circuit that I used until now, but I need more pwm channels, so I can't use the F28335.
So, I would like to know if you can sell to me the revision of the f2837xD controlcard without these issues for a price lower than the regular U$159.

Best Regards,

K.K

    K.K,

    Yes this is likely related to the Device revision. As this was a pre-production F28377S, it is understood that there may be changing parameters. The latest revision of the silicon will be improved. I am looking into your options on getting the latest revision. I will hopefully have an answer for you in the next few days.

    Regards,
    Mark

    K.K.

    Typically we do not provide free sample EVMs to anyone who requests one.
    For EVMS requested by university faculty or student organizations you may be able to reach out to https://university.ti.com/en and use the Contact Us form for more information.

    Otherwise, the only option is to purchase a new EVM.
