More discrete R2R Mulibit dacs.


There are many now going to the trouble of doing discrete R2R Mulitbit now that the last/latest Burr Brown PCM1704 multibit chip is no longer available "rip".

kalaliSo, all those discrete components combined replace one chip?
Yep, and they stopped making them years ago, because  Delta Sigma was more than 20 x cheaper to make and allowed for dsd use, probably because there was no laser trimming to be done like in an r2r ladder multibit dac, the last true ladder mulitbit being the Burr Brown PCM1704. It was only 24/96 this thing above can do  24/382

There's always the Analog Devices AD5791 that's used in the Schiit Yggdrasil.  Granted, it's only 20 bit, but it's still a true R-2R ladder.  And expensive at minimum $60 a pop.
Yes the AD5791 is still available but it was never designed as an audio dac, I don’t know what the down sides are for this in audio use. I believe the last audio one was the PCM1704 and it was more like >$120, a Delta Sigma is like <$10.

Medical instrumentation Test and measurement Industrial control High end scientific and aerospace instrumentation."

Cool looking Dac but seriously Denafrips? That might be one of the worst names for audio gear ever :-)
