Julian - that's a very good approach for lowering the noise, although it looks like the groundplane is shared. There's little room for improvement other than physical separation of psu, digital and analogue onto separate boards.
However, we're talking more about interconnection of noisy devices than internal design. Any steps taken to minimise internal noise will be a positive thing, although it could possibly increase susceptibility to noise injected from the input (because it isn't so swamped by the internal noise).
