Have you attempted reading the datasheet? There is very little to "design". It's also trivial to interface to a micro, much simpler than a PGA23xx and can make a great beginner's project.


Im interested in last post schematic by the Italian guy.It seem to be more simple but i dunno if that really work.
 
Just a note, you can turn any potentiometer to a lower value by just connecting a rasistor parallel to its two side pins. I have tested this on a DS potentiometer of 50K and it works. I managed to make it 1K 🙂

So you can have any value potentiometer up to 100K, that is the wighest value of DS
