Zener voltage divider

Hello,

I'm trying to build an external Aref from a Zener Diode voltage divider. In order to select te right resistor I want to know how much current will the Aref pin sink?

Thanks in advance

Have you read this:- http://arduino.cc/en/Reference/AnalogReference?from=Reference.AREF

Yes a couple of time in the last 2days

My mind must have skipped the info.

Thx for the answer!
