RMAF 11 Noise-Shaping Sigma-Delta Based DACs, Martin Mallison, CTO, ESS Technology

[@AJH.1957]

Despite being 7 years old, the explanation is quite reasonable to understand the sonic superiority of the ESS DAC devices, especially the ES9219C, in portables. Thanks to Mr. Joseph Wan, from ESS, for indicating this work.

This man has a real talent for explaining this very clearly

[@mhr4778]

MY GOD that noise shaping example was incredible!!! Wow!

[@stanleyyyyyyyyyyy]

Brilliant and wonderful. One of the best videos on this topic I have ever seen!

[@aaronmathias6739]

Fantastic Primer on Delta Sigma modulation & ESS in general. Simply Superb!!!

[@robcotttam8217]

This man is brilliant. Really informative. Thank you.

[@sarode123]

Awesome facts about brain-eye bandwidth, and the ear!

[@untitlednewuser]

Very informative, great vulgarisation.

Wonderful presentation!!!!!!

[@lucr1369]

Very good explanation. Loved it

[@DamnHeadHumpers]

Fantastic!

[@karlivares8401]

Great !

[@doncornell6893]

Good stuff

[@Nightjar726]

Too bad ESS chips sound blah. Super good video tho

16 bits cannot give -120dB as on the chart in red at 12:00. -96dB is a minimum. So, I think ESS tries to represent their products better than they are )

[@shuyuanliu9797]

96 dB is the maximum dynamic range a 16-bit DAC can have. Although the graph reaches down to -120 dB, the maximum was -60 dB, only spanning 60 dB of dynamic range. You would be right if the graph was in dBFS, where the largest output is at 0 dB and the curve shown would require 120 dB of dynamic range. But he said -60dB was a millivolt, implying it's not dBFS. It's possible that that DAC was some small-signal kind and only outputted a few mV maximum, then the graph is completely possible.

@@shuyuanliu9797 Aha! I was blind. Good catch!

[@xuser48]

I prefer CS over ESS.

This guy can’t prove his R2R DACs are better with measurements or a double blind test. You just have to believe.
