Discrete 3rd-order delta-sigma audio ADC: stacked KiCad PCBs, SPICE simulations, 3D-printable enclosure, and laser-cut acrylic top
Assembly guide & bench log · Bring-up log, 16–18 September · 16 September bench plan · 6 September test handoff
All four boards are assembled and bench-screened with the AD3 (16–17 September): power, rev B digital with the on-board crystal Pierce, both channels and the full stack pass, after resoldering a crystal leg and swapping the reference op-amp U2 to an LM358 for output headroom on the charge-pump rail (design-notes §10b′). A Raspberry Pi 4 captures the stream, and a ripper service on it records sides automatically, splits and tags the tracks and hands finished albums to the Jellyfin…
