In the datasheet of AD7682, I found something strange. In the table of absolute maximum ratings, it said that VIO to VDD is -0.3V to VDD+0.3V(table 6 at page 9 of the AD7682 datasheet).
Does it mean that VIO - VDD is >0.3V and <VDD+0.3V? However, the reference of specification is VDD=2.3V to 5.5V, VIO=1.8V to VDD. Is these two statements contradictory? And what is the correct meaning of "VIO to VDD is -0.3V to VDD+0.3V"?
Thank you very much!
