beginner or professional, it makes no difference: An internet search is your friend.

Most of the hits will give you the informations you want to know.
No need to go through several datasheets each with many hundreds of pages.
A good document seems to be: "7 Series Product Selection Guide - Xilinx"
If no DAC is mentioned, than it´s very unlikeley that there is a DAC.
