Hi Kirby, Thanks for your answer. So I have again two questions : - In this case, why in the datasheet with cannot have a voltage above Va + 0.3 (and not 5.5V) on digital IO? - What is the inpact of having digital IO at 3.3V without Va powered. If I'm right in this case ESD diode will not turn ON and the DAC will not be stressed? Thanks
