Our datasheets usually contain a Layout Guidelines section...as well as a Layout Example...
There are two common approaches to PCB grounding when working with mixed signal devices:
While there is no one right way of laying out a PCB, we see some advantages to using the 2nd method (the single-ground plane):
We are glad that we were able to resolve this issue, and will now proceed to close this thread.
