Analog Supply Voltage

Quick question. I am using 5 analog linear Pots as Analog Inputs to A0-A5 on a Teensy 3.2. Do I use AREF and AGND as the supply voltage, or any available 3.3 volt and gnd pin? My gut tells me any 3.3 volt pin available and AGND from looking at the schematic.

Your gut is pretty much right

Aref is an INPUT you can connect to a 0-3.3V supply to reference to. So if you wanted to be really precise you would use a high precision DC supply to drive the pots, and also feed that to the Aref pin (and enable it).

For most user input puts the normal 3.3V is fine.
