More documentation for the ADC PMODs

Yeah, I didnt connect the power source (none of my PMOD boards require additional power source, well my bad). Anyway, could there by a proper datasheet to this board ? Information regarding powering the board is provided only indirectly, in the schematic. Also, what is the voltage range I can measure ? The reference voltage doesnt seems to be directly stated anywhere, except schematic file, where there are 2 voltage regulators with unknown output voltage.

    Hi Martin,

    As mentioned in the previous post, the external power is needed to achieve the datasheet performance specs.  It's not like other typical PMODs where the power is supplied when plugged into the port.

    The ADC input range is still very much going to depend on the reference voltage(ADR435 = 5V) and which version of the PMOD you are using.  Because there are 15 devices in this family you'll still need to refer to the part datasheet to determine the individual input ranges.

    I've got it on my radar to create some more documentation for these PMODs, but at this moment in time I am swamped with several other projects right now.  The guy who originally did these is no longer with the company, so it's one of those things I'm trying to get to, when I have some extra time.
