More later but for now..................
AD5791BRUZ - Headline specs: 1 ppm 20-Bit, ±1 LSB INL. We use 2 per channel (1 per phase) to get an honest 20 bit level of performance. That is four per Yggy. The BRUZ version is the higher specced model.
I know only 20 bits you say? You can get a 24 delta sigma bit (advertised) DAC chips for 3% of the cost of one 5791. Check it out. Go to Mouser or Digi-Key and see how much AD5791s cost. Yup, you get just about $400 worth of DAC chips in every Yggy. I have seen $10,000 dollar D/A converters with $22 bucks worth of dac chips inside. The Yggy is by far away the best fu***ng parts cost deal going in the arena of high end DACs
Biggest problem was figuring out how to get it running without glitching - sample and hold amps sound like ass.
Also you have to drive it with DSP because every sample requires a fixed preamble.
For the above reasons, I don't expect a lot of competitors to be using it. After all, even analog devices told me it was not designed for audio. The best way to get me to do something is to tell me I can't or shouldn't do it.
