I use ad7616 in my board.
after operation for a while, my system turned out to be unfunctional.
I checked components on the board and found ad7616 was not functional.
I read out data in Regs of ad7616 after setup, all values were 0x8000.
I tried to read out conversion results after a convst pulse(no busy signal generated by ad7616), all values were 0x8000.
I also have other boards and all works well.
Is my AD7616 broken? how to diagnose？
