Seperating analogue and digital grounds

Post by ice-nine »

Hi, I am making a pcb project at the moment which is not too complex. It will carry a ground plane on the underside of the PCB. I am just wondering if it may be that the Agnd and Dgnd would benefit by being separated.

I haven't read any info on how these Gnds are connected within the FV-1 so I am unclear If it is necessary to separate them.
Thanks

AGND and DGND are connected in the FV-1, separating on the PCB depends on a number of factors but it usually not really necessary.
