DIY DAC Board – AD1852 + DIR9001+ NE5534, 24BIT 96KHz, SACD

Description

This is the 5th (latest) version of DAC. I’ve been keep investing on this AD1852 based design since 2012. So it is not a fancy but well optimized, ulta-low noise and THD design. The LPF has been being improved based on thousands of international users – see the measurements below on the real product.

Parameters:
PCB Size: 140*138MM
Power supply: 2*15V AC, 9V AC, Max 15W
Input: USB, Fiber, Coaxial
Output: L/R RCA

Features:
* support 24BIT/96K. Digital input sampling, compatible with SACD 96K playback
* digital analog separation PCB design, 5 sets of independent power supply
* Ultra-low jitter (<50ps) receiver DIR9001 on digital reception interface.
* AD1852ST5 DAC + NE5534 (one piece per channel)
* Excellent circuit design and PCB manufacturing allows extremely low THD and noise

Measurements
* Extremely low background noise: <-120bBV at 0-1KHz, <-130dBV at 1-20KHz, in both input shortcut and digital mute stage
