Hi Richard,
 
There's really nothing to post. I copied the circuits directly from the application notes for the THAT 1646 and THAT 1246 chips. You can find PDFs of the app notes at THAT's website. Arguably if I did post my circuits it would be a copyright violation. :-)
 
The chips are dead-simple to use. The only external components you need are some caps that are actually optional but improve performance somewhat (if I remember correctly). You can order the chips from Mouser although they don't seem to carry the entire THAT line.

Can you post a circuit schematic diagram, Adam?

Thanks,
