My customer has a design that has been working for many months but is now seeing that the I2C communication is being lost with the AD7994. Are there any unpublished or common issues seen around the I2C interface? Thank you!
I would like to ask some question so may we have a better understanding of the problem. When is the communication loss? Is it getting loss all the time or a certain period? Is there a pattern when it loss the data? From the design, were there changes in component values used or were there new component introduced?
