Dear Freaks,

Can i connect the voltage on the Aref pin (ATmega1280) via a pull-up resistor to and A/D pin? I'm using the internal 2.5V AD voltage reference. How much current (if any) can the Aref pin output?

Kind regards
Bjorn

No noticable load should be connected. So you can connect the input of an opamp,
but not much more.
