ADC in x20


#1

Hello,

I wanted to check if i can use the ADC on the X20. From the schematics, I was not able to find out if ADC can be used.

Can anyone suggest me any idea to use ADC in X20?

Hi there,

Have you checked X20 functional specification: https://www.dropbox.com/s/q47mnr3ejvqaa8k/MT6797%20LTE-A%20Smartphone%20Application%20Processor%20Functional%20Specification%20for%20development%20board%20V1.0.pdf?dl=0

I searched a bit for the doc, X20 has AUXADC modules for thermal and light sensor. Not sure if this is you are looking for.

Thanks,
Leo Yan

Hi Leo,

Thanks for your reply. I agree that AUX_ADC will serve my purpose. But according to schematics page 6, in AUX_IN section, the 5 ADC channels(AUXIN0, 1,2,3,4) were not pinned out. So, I believe I cannot use it from processor (MT6797).

Is there any way I can get an ADC from PMIC (MT6351). Where can I download the datasheet for the PMIC (MT6351)?

Davidson. K

Hi Davidson,

Mediatek X20 Board didn’t pulged any ADC pins out, and the Datesheet of PMIC(MT6351) was not published.
