Once in another thread somebody made a joke, why not use a DAC for every single bit...
Now, this would be not too complicated with parallel input DACs like PCM53 or PCM54 or even PCM64 which is 18 bit.
A lot of chips could be tested and selected for matching output current or better voltage after I/V with theoretical value.
Even the previous or next code could easily be chosen if matching.
When using PCM64s to built a 16bit DAC, the best code could be chosen from those inbetween extra bits.
