Hi, in the datasheet page24, it sounds the ENOB equation is NOT correct, please help double check how to this ENOB calculation in equation 2, thanks.

Hi Jay,
Thank you for your post.
Technically, you are correct. What we are calculating in Equation 2 is technically called "effective resolution," not ENOB.
ENOB is actually calculated from SINAD as: ENOB (bits) = (SINAD - 1.76) / 6.02.
