- Very high performance; measurement results with coaxial S/PDIF input:
- Output level: 2.0 Vrms
- Dynamic range / SNR: 122 dB (A-weighted)
- THD+N ratio: -103 dB (0 dBFS/1 kHz signal, 48 kHz sample rate)
- Crosstalk: -128 dB at 1 kHz, -112 dB at 10 kHz
- Supports S/PDIF, Toslink, USB, and external I2S inputs
- Unbalanced outputs (RCA) on board, balanced (XLR) addon available
- Hardware-controlled – no need for microcontroller (but one can be added with addon)
- Can be powered by AC or DC supply
- Addon available to transform H-DAC into preamplifier/headphone amp
- New output stage addons can be easily designed to experiment with components and circuits
- CS8416 S/PDIF-receiver, PCM1794A DAC, LM4562 opamps (or any SO-8 dual opamp), PCM2707C USB-audio, LM2940/LM2990, TPS73633, TPS79133, and REG103 regulators
H-DAC is a high-performance 192 kHz / 24-bit capable DAC board with TI PCM1794A DAC. The board has two coaxial S/PDIF, two Toslink, and one I2S input that can be either on-board 48 kHz / 16-bit USB receiver or an external I2S-device. Input selection and settings are controlled with jumper links that can be replaced by mechanical switches or microcontroller addon board.
