From practical point of view I tried both connecting the shield to analog gnd input and left the shield unconnected and I got better results (less noise and higher measurement stability) in the first case so I kept it connected.
I also live close to local radio station so I have alot of RFI which didn't sneak in to the Analog gnd which could be due to ferrite beads. Mahmood |
