Hello,
looking at the ADS8698 datasheet, I can see on page 3 & 4 that REFSEL is located on pin 4 and DAISY is pin 3.
On the other hand, on the layout example (figure 112, page 68) I see that REFSEL is pin 3 and DAISY is pin 4.
My initial guess is that the PIN description on page 3 is the one which is correct, could you please confirm that?
Thank you in advance,
Alejandro
