Very high performance 116dB SINAD (typical) 768kHz/32-bit balanced AK4493S-based DA-converter.

• Power supply separation for improved performance:
  • Separate Left/Right high performance LT3042 regulator providing analog supply and reference; optional dedicated VA supply input for these.
  • Separate regulators for DAC digital and clock interface.
• Output stage with 3rd order Bessel low-pass filter with excellent timing and phase coherence.
  • OPA1612 opamps, C0G capacitors, and thin film resistors.
• Clocks and digital audio via U.FLs for improved signal integrity and reduced interference.
• Relay output mute to attenuate power-up/down glitches.
• Transparent design – schematics are available and performance is backed by measurements.

Choose from the following product options:

• Control:
  • HW-control for easy plug-and-play I2S-operation.
  • I2C-configuration for more complex settings. Only this variant supports DSD. Requires I2C-host and register configuration.
• Output:
  • Stereo XLR (4 Vrms output).
  • Stereo RCA (2 Vrms output).

The board is delivered fully assembled and tested.

Additionally, to connect the DAC in your system, we recommend the following products:

• U.FL cables and U.FL to header adapter for connection between boards.
• 6-pin power cables and One Four All PSU for power.
• Clock Buffer 1-4 if splitting I2S/DSD clock signals is required.
