Is this your own design board or a development board?

If the latter then you need to confirm check how you release the ADC IP from reset. Hold it in reset 'a little longer' following power up. Sorry this might sound a little vague. This seems to be a regular issue on the forum that doesn't seem to have received a clear, reliable solution.

If this is your own board then you need to check the above and ensure the rails rise monotonically. There are no sequencing requirements but if the don't rise appropriately - not meeting the Tramp time - the device will misbehave. Refer to 'Figure 3. Monitored Power Supplies Ramp Up' in the 'power management user guide (https://www.altera.com/en_us/pdfs/literature/hb/max-10/ug_m10_pwr.pdf)'.

Cheers,
