One thing, I want to add for 14 bit DR sensor, there might be benefit to process with higher bit DAC to achieve truly 14 bit performance. People do this all the time with CD player which is red book 16 bit but process with 20bit and even 24 bit to implement digital cut off filter easier. Admittly, It is not purely for performance, but just industry standard, and consumer do chasing number/spec thinking 20/24 bit must be better than 16 bit.
I can see the reason for 18bit to achieve real 16 bit performance but not 20/24 bit.
For example, a state of art 24 bit dac can achieve close to 130dB DR a little short of 23 bit performance.
From cell phone, sorry for typo.
