Another approach is to star-point the different grounds near the analog ground signal on the
microcontroller by using small traces for connecting the non-analog grounds to the analog ground. The
small traces are meant only to accommodate DC differences, not AC transients.
Other suggestions for PCB layout in which the QADC64E is employed include:

reference inputs from the power supply signals allows for additional external filtering, which increases
reference voltage precision and stability, and subsequently contributes to a higher degree of conversion
accuracy.

Analog ground must be low impedance to all analog ground points in the circuit.
Bypass capacitors should be as close to the power signals as possible.
The analog ground should be isolated from the digital ground. This can be done by cutting a
separate ground plane for the analog ground.
Non-minimum traces should be utilized for connecting bypass capacitors and filters to their
corresponding ground/power points.
Distance for trace runs should be minimized where possible.

This star-point scheme still requires adequate grounding for digital and
analog subsystems in addition to the star-point ground.
