Currently reading the datasheet of these components, I wish to ask you some more information about the power-up sequence.
On page number 24 of the datasheet (revision C), I can read that the ideal power-up sequence is : 1.VSS, 2. VDD and then Va/Vw
But on the AD5272 FAQ (http://www.analog.com/en/digital-to-analog-converters/digital-potentiometers/ad5272/products/technical-documentation/index.html), under the question "Is there a power-up sequence?" I read that the power-up sequence is 1. VDD, 2. VSS and then Va/Vw
So I wonder which sequence is the right one? Is it really important ?
I thank you
