Thank you for the explanation. While it does clarify a few things I still have some questions.
What prompted my curiosity is an article I read (linked bellow) that shows an 8-bit R-2R DAC that's basically comprised of 8 pairs of R/2R resistors - one pair representing each bit. Knowing that monolithic multibit chips such as the BB PCM1704 are basically laser trimmed resistors on a silicon chip, I simply wondered why can't the resistors on the chip be combined with outside discrete resistors to form a ladder network able to resolve a 24-bit word-depth signal.
Since my knowledge here is very limited, I know that I am probably oversimplifying things, so any light you can shed on this will be appreciated. As an example, why would BB put two 23-bit dacs to create the collinear architecture when an extra set of resistors (either as a single pair or multiple same-value paralleled pairs) would 'presumably' have worked. I know I'm missing something, hence my simplistic questions.
