An issue about AD7151



I encountered a strange problem while using AD7151 as a capacitance sensor in my current smart hardware design.


AD7151 suffers from serious reading drifting in a specific circumstance where the capacitance should be fixed, but is reported as continuously and slowly increasing (data register increments by one every approximately 5 minutes.)


I wonder if this is normal and what can  I do to stress this drifting problem.


Hopefully I made myself clear and feel free to ask me about the configurations of the chip and other design details.


Any comment is appreciated.
