With the method described on Bytecraft's web page, you
can get as much resolution as you want. You are only limited
by :
1) Sample speed (no problem with the Scenix)
2) Hysteresis on the input

Have a peek : http://www.bytecraft.com/addaconv.html

If you want plenty resolution, you can use a comparator on
the input.
