DAC8760 in daisy chain

Other Parts Discussed in Thread: DAC8760

Hi

I am going to use  four DAC8760 in daisy chain in my new design. The board need to be released in November.

As per the data sheet, in page 39, SDI and SDO were linked to chain muti DAC8760.

Can this daisy chain wired after the isolator ISO7631 at MISO and MOSI? ( page 47 in the data sheet)

I am creating a block in the schematic that capture the DAC and the isolator.

Find bellow my schematic block.

Appreciate your guide and I am going to have a design review next week Tuesday.

Also is there a SPI code with daisy chain that inteface the DAC8760 to the CPU I can download?.

    I apologize for the very late response - I was reviewing our forum coverage and noticed that no one has answered this question and, unfortunately, this response is coming well beyond your November target for design review.

    Your schematic block diagram implements the daisy chain feature correctly. I do not have a complete code example that implements the daisy-chain feature but there is a basic code library available and attached for your reference.
