TS86101G2B AGND and DGND Ground Planes

How do I have to connect the A2 and A15 AGND pins of the
TS86101G2B 4:1 10-bit 1.2 Gsps DAC?

First, it is important that the AGND and DGND planes be separated
at the board level. This being said, it is not necessary to use
different layers for AGND and DGND.
A simple way to connect the AGND pins (A2 and A15)
to the AGND plane is illustrated in the figure below:
