There is more! I started to figure out how ADC/DAC chips actually work. I believe our CM6533 and its competitor the CM108 both use delta-sigma. The output isn't a staircase of those samples but a rapidly switching (MHz rates) 1-bit modulator (think: PCM) output, and a final analog filter smooths it into a continuous waveform.
