Tom,

Note sure if this will help, but Colin Fraser sent me a link in August of this year as part of a thread I started called "Micro as a Linear to Exponential converter?"

http://www.sequentix.com/gx1/

He also mentioned that he'd been using a 4051 Mux to get 8 outputs from a LTC1597 DAC.

Maybe there'll be some info there.

I've recently started using a TLV5618 Dual 12-bit DAC driven by an Arduino/ATMega 328 and was hoping to do what you're trying to do using a 4052 Mux - so I'd definitely be interested in your progress.

HTH,

Justin
