Greetings,

It is preferred to completely separate these two GNDs. Alternatively, there could be two GNDs. Then at one point, provide a choice to either have a ferrite bead or zero ohm Resistor to connect these two GNDs. Using a ferrite bead ensures high frequency noise from digital side will get heavily attenuated.

Greetings Prashanth,

I just checked DS160PT801 evaluation board schematic and we use a single GND for both digital and analog. Suggestion is to follow evaluation board schematic/design. Typically it is preferred to separate digital and analog GND however it is not in this design.
