I am currently using 8 AD4682 chips for 8-channel sampling voltage, of which 7 output values are normal and the 8th output value is incorrect. The specific error is suspected to be that the 8th channel directly outputs binary source code, but the specification book stipulates that the output should be binary complement, and the other 7 channels also output complement.
Compared to another similar product, its specification clearly states the method of configuring internal registers in the output format of source or complement. Can AD4682 also adopt a similar configuration method. According to the datasheet, the follower used is AD8606.
The current investigation has swapped one of the AD4682 circuits with the eighth circuit, and it was found that the problem still lies in the eighth circuit. What should be investigated next? There is no good idea, help！
（我现在用8颗AD4682做8路采样电压，其中七路输出值正常，第八路输出值错误。具体错误疑是第八路直接输出了二进制原码，但规格书规定了输出应为二进制补码，另外七路也是输出了补码。
对比另外一家的类似产品，其规格书明显说明了输出格式为原码或补码的配置内部寄存器方法，AD4682是否也可以采用类似的配置方法。按照datasheet中所用跟随器为AD8606。
目前已做的排查有将其中一路AD4682与第八路互换，发现问题还出在第八路，请问接下来该排查什么？没有什么好的思路，求助。)
