Hello，
我在使用AD7151测量电容值时，遇到一种特殊的情况，在被测目标电容值（Data Register读数2600左右）较大的情况下，Data Register里的读数（本应该为常量）却每隔大概五分钟增加一。在电容值较小的情况下（小于2600），没有出现这种漂移的情况。
我的外围电路和驱动我反复检查了，应该没有问题。不知道这种情况是否常见，是有可能由什么引起？
谢谢
Hi,
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.
