FEATURES
1. This is assembled PCM58 x4 DAC, which can be used with PCM1702 x4 or PCM1704 x4 by using the come with adaptor boards (CS8414, PCM1702 x4 and PCM1704 x4).
2. DAC output can be set by either 4 parallel PCM58/PCM1702/PCM1704 or balanced.
3. PMD100 adopts 44.1kHz/20bit coding for HDCD.
4. The first OPAMP stage for I/V conversion and the second OPAMP stage for low-pass filter. OPAMP can be used either AD797 or NE5534 or OPA627.
5. Power supply unit is done by 2 steps: the first step uses MJL1503 and 15031 for voltage regulation; second step uses LM317 and LM337. Totally 10 independent power supplies can be adjusted by resistor trimmers for inner core circuitry.
6. Dale resistors and Motorola MR756 rectifying diodes are used.
7. PCB Dimension: 25cmx25cm, 2.4mm thickness, 2oz copper.
This DAC includes ICs: PCM58Px4, CS8414, PMD100, 74HC86 and NE5534x12. Including all the components as shown in the photo.
