Hi, I need to connect 12 potentiometers to the adc inputs in the BBB (through an analog multiplexer). I have found that if I use potentiometers with lower resistance values (2Kohm), the input is less noisy than if I use higher resistance pots (500KOhms). Since the pots are "powered" by VADC and AGND (1.8Volts), I need to know how much current I can draw from these two pins. Anyone? :)
