Amir has a thread on the fundamentals of sigma-delta DAC. As Don has alluded to, the highest performance audio DACs these days are sigma-delta.
However, I have in my plan to write a post on DACs that use sample-and-hold, which is the most intuitive method and therefore how DACs were first implemented. This produces the stair-step waveform (see post #2) as part of the digital to analog conversion process. I just started preparing the materials and hopefully will have a post by this weekend.
Delta-Sigma Digital Audio Converters (DAC)
Note: this article was originally written by our DAC/technical expert, @DonH56. The previous thread on DAC fundamentals provided an overview of conventional (Nyquist) DACs. This thread will introduce oversampling and the delta-sigma architecture that dominates the DACs used in consumer audio...
