To make a 24-bit NOS DAC, all you need are two PCM1704s, one inverter, and a DIR that supports 24-bit, right-justified operation.

But why would you wanna do that?? You will not use 8 bits of the 24.

Thank you so much whatsup !!

QserraTico_Tico, I belive newer converters are better than the older ones, at least som of them!
Also If you can use the 16 upper bits in a 24 bit converter, then you have liftet the signal up above the worst noise and unlinarity in the converter. In other words cleaner signal.
Maybe somone can confirm my filosofi?

Maybe, all my 20 bit converters PCM63 and PCM1702 were clearly beaten by selected and well adjusted PCM56.

But I would be interested in trying PCM1704 too.

The OP asked for a diagram; the choice of DIR is up to him. As I said, any DIR with 24-bit, right-justified output will work.
