Dear  Sir/Madam,


I am using AD7156, when i use it, I found that  sensor cap is made on the same PCB layer. In fact, according to general theory, the  counter electrode of the cap should be one down and one up. And thus I am confused about it.

In addtion, if  I want to use external cap sensor on CIN/EXC, what should I do.
