Hi David, I think I see another potential problem in your setup, after you are doing an ADC reset the init bit of the ADC does not seem to be reading back "1" which would indicate that the part completed all of its initialization process. See reg description below. This issue could be caused by the device not receiving a clock to run off. In your schematic I can see that you are driving the clock differential but I cant tell what the source of this clock is, is it an on board oscillator? If so can you please probe this input to the ADC and confirm that the clock signal is there. Thanks, Eric
