The 4 ways to decode digital

-Commercial DAC-chips. Resistors, representing 1 to 6 bits, except Burr-Brown 1704 (24). But the Burr has only 18 bits of resolution. The most common type of DAC -inc. Delta-sigmas and hybrid/multi-bit.

-Programmable and discrete logic. Using (maybe 4) "latches", this approach relies on field-programmable gate arrays (FPGAs) for DSP. A system that emphasizes instructions (vs. operations). Possible to remove a few clocks and use a passive output stage. Playback Designs and PS Audio idea.

-Discrete resistors (in a foil-ladder configuration). Doesn't use a current-to-voltage converter or digital filter. Totaldac is one.

-Reformatted then switched. From PCM to PWM - Lyngdorf and NAD digital amps.
