Parallel DAC vs multiplexer

Problem with multiplexing DAC outputs is it needs a separate
break/make sequence for the mux, giving 3 commands over the SPI bus,
probably reducing speed quite a bit.

Unless the mux is controlled digitally like a MAX336.

Let's start looking for multichannel DACs with at least 12 bits.
