Hello,

I have a question regarding the AD7746:

How to use eval-ad7746 to measure two capacitance values at the same time？

Thank you

It is not feasible to measure two capacitance values at the same time using a single AD7746, as there is a analog multiplexer which switches alternately between the two capacitance values. You have to use two AD7746 to measure the two capacitance values at the same time.

So I can't use EVAL-AD7746EBZ to measure two capacitors at the same time.
