AD5664 issues

Can I clock the AD5664 32 times, and have just the first 24 bits work properly? I need to share the SPI interface with another device, which will work if the DAC accepts 24 bits and ignores the rest.


On the data sheet, fig 29, the output amp is shown as having a gain of 2. That seems inconsistent with the equations. If I use a reference of +4 volts, what will the maximum output be?


The data sheet, rev 0, is 11 years old. Is rev 0 a preliminary draft?


Incidentally, it's very hard to find the place to post a question to this forum.
