Hi Jeremy,

Thanks for clarifying this, sure we can double decker 2 ADCs.....at least
they won't be lonely :)

@ 1.5v PP is not a good idea if you have Penelane/lope anywhere near it),
there is also the issue of correctly correlating the data from the two
boards as you have already pointed out, in fact the thought of adding a
second ADC on Hermes did accur to me when I was working on the PCB but trust
me looking at the component density and crosstalk issues I immediately
discarded the notion,
