AVR-Chat

Thanks Jim for clear answer. I spent about an hour searching the net with no clear answer. Posting a question here on avr-chat would give me an answer faster:) 
 
cheers,
mago

Flatness tells you how much the on-resistance varies with voltage over 
the range of allowable voltages. Thus, I would expect 0.5ohm flatness 
to indicate that the resistance will be within a 0.5ohm "window", 
maybe with an average of 2.5 ohms or maybe 2.5ohms at some nominal 
voltage (probably given in the spec sheet).
