AD5791 daisy chain

Q 

We are going to use 4 of this IC in the new design, and we need to optimize
digital IO count. We were planning to use them in a daisy-chain structure until
I saw in the datasheet revision history that daisy-chain section is deleted.
Does it support daisy-chain like the AD5764, or not?

 

A 

Unfortunately we cannot guarantee that the part will work in daisy-chain as it
was in the old datasheet. All open market documentation has been revised and
was posted accordingly. The daisy-chain functionality will no longer be
documented as an option for the AD5791/81/90/80/60.
