Pretty confident we do these in a ring arrangement; a challenging PCB and/or print job! See PDF at https://raw.githubusercontent.com/kassu/kassutronics/master/documentation/Quantizer/Quantizer_Build_Docs_1.1A.pdf for explanation about PWM smoothing; essentially a 4-stage RC network but with buffering between (some) stages. Needs a TLC7524/AD7524 (a simple DAC that's still sorta analog) and a "work based on infringement of intellectual property rights needed, if any. For example, if a court requires any other Contributor, and only if You explicitly state otherwise, any Contribution become effective for each.
