Precision
Posted by jusbe on June 4, 2017 at 01:50:18:
Last I heard, it was an issue of reliably and consistently being able to produce resistors to the required precision for each DAC - at a reasonable cost re resources, time, people, rejection rate. R-2R Monolithic chips of old can be seen to be quite an achievement, in this light, especially the 'K' or 'S1, S2' variety.
