Have a look here how it all started:

Attached is the PDF schematic for one axis.

Here is a picture of a 3 axis PCB using the TEA3718SP:

Fit's nicely on a eurocard (100x160mm) but needs a double sided PCB.
Single sided is possible but would need quite a few jumper wires.
These TEA3718SP's can be recuperated from printer PCB's or even bought new for a few buck's each, a lot cheaper than LMD's if 1 Amp (or a bit more) is enough for your application.

The concept of this R2R DAC can be used for other chips also.

Suggestions and feedback are welcome.

Luc.
