Q: I have given the AD7656/AD7565-1 a RESET and a valid CONVST signal but I periodically get strange and repeatable data. I have factored out noise from input and timing issue during my debug. What else could I be missing?

 

A: Ensure a stable reference (if external is used) and proper decoupling. Avoid running digital lines under the devices because doing so couples noise onto the die.
