Hi guys.
I bought a little AD7924.
I tried to use it, but it did not work well.
Several experiments have shown that the CSB and DIN (MOSI) of the SPI interface are reversed from the datasheet.
I would like to know if the AD7924 I purchased is faked or defective.
The chip is marked as follows.
7924

# 551
Please answer.
