The diode is not necessary.
The AC coupling cap is required on both legs as well as the MICBIAS resistor to provide bias to the ADC input pins. Check the diagrams in the data sheet for references on this.
There is a link in the datasheet to a tool…
你好，
你能提供你正在使用的MCLK、BCLK和WCLK吗？为了我的理解，我已经注释了你的登记簿，我也会把它放在这里。如果你能在测量失真和频率折叠时提供示波器（信号和时钟）的屏幕截图或图片，那也很好。

Okay, I understand. I think I missed providing some information—this is the schematic diagram of the inverting amplifier.

I tried connecting an electrolytic capacitor in series between the input of the ADC and the output of the amplifier circuit…
Hi,
I am currently conducting lab 1. After debugging, the ADC is functioning normally, but there is no 0.5 pu output. The input is then sent out through this rectifier bridge. Could you please offer me some suggestions?
