Hi, all.

 

I have one question about AD7689.

 

 

I have already finished hardware design.

However I took a mistake.

I refered to the old datasheet so I connect 2.8V to VDD nevertheless I use internal reference.(2.5V)

 

And please let me know if VDD is connected 2.8V, what kind of effect does AD7689 have?

 

 

Thanks.
