Morten, du kunne jo også bygge din egen (næsten) helt fra bunden. Hos
DIYINHK har de forskellige multibit byggesæt (TDA1540/TDA1545A/AD1856/AD1862/AD1865/PCM1702/PCM1704). Herunder er en multibit-chip oversigt lånt
herfra, med egne tilføjelser i
blåt. Kommentarernes lødighed kan jeg ikke vurdere, men oversigten som sådan er jo fin at have med sig, når man er på udkig efter en multibit DAC. Der findes også denne
oversigt over (tilnærmelsesvis) alle chips i CD-afspillere og DAC’er fra de sidste mange år. Er man på jagt efter vintage multibit-lyd er listen en guldgrube. En mand med dine evner, Morten, burde kunne puste nyt liv i en af disse gamle maskiner
MULTI-BIT
Burr-Brown (Variants: U=SOP / P=DIP)PCM51, PCM52 – 16-bit predecessors PCM53, a ceramic package
PCM53 16-bit, one of the old, but good (1983-86 years), with a parallel input
PCM54 16 bit multibitnik normal (slightly older PCM56), parallel input
PCM55 16 bits, the same as the PCM54, only in a small SOIC package
PCM56 16 bit, normal quality multibitnik
PCM58 18-bit, a very good DAC
PCM61 18-bit, the quality of a PCM56, but 18-bit
PCM63 20-bit, one of the best of the world’s Audio
(Grades: P, P-1, P-J, P-K, P-K-2 and P-Y)PCM64 18-bit, one of the best, with a parallel input
PCM65 – one of the best, most expensive and rare multibitnikov, with parallel input
PCM66 16-bit DAC-2 and, huddled in a single housing, the quality – so so
PCM1700 18-bit, 2-DAC and in one case (stereo), the quality level PCM61
PCM1701 18-bit, one of the best, the successor technology PCM58
PCM1702 20-bit, the quality just below the PCM63
PCM1704 20-bit, the same as the PCM1702,
but only able to accept 24-bit stream (converting all the same 20-bit)
