Can an output of 0.0V be reached?

Right now, when I write an output of 0x00 and I mesure it, I get 0.6V. Perhaps its my design or maybe 0.6V is the lowest output that can be reached. I really don't know.

Thank you very much.

The quick answer is no - the range is something like 0.6V - 2.7V. This has arisen in the forum before, so I think you'll find more detail with a search.

Oh, I see.
Thank you very much.

The range is 1/6th Vcc -- 5/6th Vcc.  You could put them through an opamp with
gain of 1.5 or -1.5 to get rail-to-rail.
