Hi I am DFAE in Japan.
AD5687R read back operation is explained as following in the datasheet.
“1. Write 0x900000 to the AD5689R/AD5687R input register.
This setting configures the part for read mode with the Channel A DAC register selected.
Note that all data bits, DB15 to DB0, are don’t care bits. “
According to table8, I think 0x900000 is wrong.
When DAC A is read back, should 0x910000 written to AD5687R ?
When DAC B is read back, should 0x980000 written to AD5687R ?
Best regards
