Connect all the input pins together, and connect them all to analogue ground. See what happens on all channels.
Release the connection to one of the input pins, and connect to your pot, which is connected to Agnd. Now see what happens on all channels. 2 LSB isn't bad - its a 12bit converter, so you are looking at 1 part in 2000 variation, albeit thats a couple of mV. Steve |
