I don't know of any with a D/A, but there are several of the Motorola
6805 series chips which have a 4 channel 8 bit A/D on it.  If need be,
you can get DAC-08's cheap, and use on of the microcontroller ports to
output to it. Either that, or use one of the outputs as a 1 bit D/A :-)

Hitachi also sells similar chips, but the A/D is so poorly specified on 
the Hitachi part, that I wouldn't trust it to anything over about 5 bits.
