AD7912: FAQs

I’m trying to capture signals using 6 x AD7912 ADC’s wired in daisy chain.
I can’t get it to work the way it is described in the datasheet.

 

It seems there is an error in the datasheet.

In figure 34 of the datasheet of the AD7912 the second 10-bit write has
"don’t care" written in DIN data.

If instead of writing zeros I write the configuration of the next channel the
first ADC is configured correctly.

Also the dummy conversion at the end of the diagram is not necessary in this
case.
