AVR-Chat

The Atmel data sheets, at least the ones I'm dealing with, say the "ADC is
optimized for analog signals with an output impedance of approximately 10 K
or less".   Does anyone have any experience about how much you can exceed
this 10 K?

I have a simple voltage divider that I'm reading the voltage from and I'd
like to minimize current consumption so I'm wondering if this can be
increased to, say 15 K or 20 K (or more?), without much detectable effect.

Thanks, Steve
