AD5686 SPI

Hey all;

This is my first discussion here at engineer zone:

We are using the DAC AD5686 daisy chain mode to end with 32 channels for an application.

I was wondering if between the DOUT of one DAC and the DIN of the other DAC a pulldown resistor is required? We are not using it currently.

We are doing several test and so far we've just connected with two DAC's not being available to connect with the 9-12 channels and so on.

Which are the commands for the SPI interface in order to set the Daisy chain and to start data conversion just to test?

Really appreciated.
