Oops, I was planning to read the rest of your posting after replying to
one bit.  Can you fix your e-mail agent so that it sends standard mail,
please?

Anyway, the MAX517 is one of many single-supply 0-5V DACs on the market.
Of course, it has essentially no current drive for outputs right at either
the supply or ground, but that will be true of anything that's swinging
rail-to-rail.  And with an IIC interface it only needs two pins for
control.
