 		 #160117 - once conneced inside ...
Responding to: ???'s previous message
.... the only thing you can do is to consider the processors ground pin the junction between agnd and dgnd.

if you want (much) more than 8 bits of precision you have a task with the grounds connected, a common method is to put the processor to sleep during the analog conversion.
