Using a single DAC with multiplexers is a bit redundant in this age of many multichannel DACs, and this particular multiplexer doesn't seem to have sufficient accuracy to make you have second thoughts ("High accuracy: 8-bits absolute, 12 bit linearity" they say in the datasheet).

I guess that depends on the relative prices. It should be possible to construct a sample and hold mulitplexer for a DAC output to 12 bit, memory moog style but I am beginning to suspect that there is no cost advantage - MAX5500A, 12 bit, 0.75INL quad output for circa $6. 

Get that deja vu feeling TimP - had a chance to play with them yet?
