Title: Due Analog Current Draw
Post by: TurboN2O on Jul 23, 2013, 12:02 am
I am trying to figure out what the current draw is of one of the analog pins on the due board. The resistance would me appreciated as well. I am working with high and low pass filters in this area of my circuit and am worried about possible signal strength and filter accuracy. Thank you.

Assuming you mean analog inputs (ADC):

See section 46.7 of the SAM3X datasheet for some good info.

I think what you're after is Table 46-36, page 1420 (Attached).
