Hi,

Searching the internet for the datasheet, downloading it, opening it and a view to the "functional block diagram" on the first page,
This needs only some seconds and the answer to your question is obvious.

There are two main 16 bit DACs.
And there are four auxilary 10 bit DACs, two of them are fix connected for GAIN adjust of the two main dacs.
And the other two may be used as auxilary DACs or for offset adjust of the main DACs.
