HiFiBerry DAC2 ADC Pro Module DAC PCM5122/ADC PCM1863 for Raspberry Pi Burr Brown 24bit 192kHz

HiFiBerry DAC2 ADC Pro picture

The HiFiBerry DAC2 ADC Pro is a DAC/ADC module for digital-to-analog and analog-to-digital conversion specially designed for use with a Raspberry Pi (A+, B+, 2B, 3B, 3B+, 4B+, Zero, 5). This sound card therefore features both analog and digital inputs, offering a wide range of uses, whether for recording or audio playback.


The module is based on two Burr Brown chips, a PCM5122 DAC chip and a PCM1863 ADC chip, enabling it to support PCM streams up to 32bit 192kHz. An optimized clock circuit completes the package, reducing jitter. The HiFiBerry DAC2 ADC Pro is also compatible with the HiFiBerry DSP add-on and Alsa Mixer for volume control.

Signal input is via 40-pin GPIO (digital) or 3.5mm jack/PCB connector (analog), while output is via RCA or PCB connector. The module is powered by the 40-pin GPIO, and therefore by the Raspberry Pi, and a PCB connector enables an additional 5V supply to be taken from the Raspberry Pi.

Key features:

  • Stereo input and output
  • Dedicated 192kHz/24bit high quality Burr-Brown DAC
  • Dedicated 192kHz/24bit high quality Burr-Brown ADC
  • Hardware volume control for DAC and ADC. Input and output parameters can be controlled using “alsamixer” or any application supporting ALSA mixer controls.
  • Supports HiFiBerry DSP module (sold separately).
  • Connects directly to the Raspberry Pi, without the need for an additional cable.
  • No soldering required, just connect to a Raspberry Pi. HAT-compliant.
  • Compatible with any Raspberry Pi with a 40-pin GPIO.
  • Three ultra-low-noise linear voltage regulators for optimum audio performance.
  • Low jitter clock for optimized clock signal.
  • Microphone bias voltage for use with electret microphones.
  • No anti-aliasing filter on the input circuit to offer the best recording bandwidth.
  • Complies with HAT format. EEPROM for automatic configuration.
  • Gold-plated RCA output connectors.
  • Supplied with spacers and screws for RPI mounting.
