ADC reference for FEZ


#1

Hey,

I’ve searched through the online documentation and forums but can’t find an answer for this:
what is the ADC reference that is being used in the FEZ Cerb40 II and FEZ Cerberus boards?

Thanks!

You can watch the schematic @ https://www.ghielectronics.com/catalog/product/349 , but i guess that VCC is used as reference


#3

@ RobvanSchelven is correct

I did review the schematic, but that doesn’t tell me what Vref is being used when a conversion is performed.
So it’s VCC. Thanks! :slight_smile:

PS: I suggest that this tip is added to the ADC documentation for FEZ.
