HiFiBerry DAC2 ADC Pro

The HiFiBerry DAC2 ADC Pro is a high-resolution digital-to-analog and analog-to-digital converter for the Raspberry Pi, which combines our well-known DAC2 Pro with an analogue input.

Both input and output support sample rates up to 192kHz. It is our first DAC/ADC board that also supports our DSP add-on.

This is a special sound card for the Raspberry Pi, optimised for one specific use case: the best audio playback and recording quality! It is specifically designed for applications that do not only need playback, but also recording functionalities.

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. You can control the input and output parameters using “alsamixer” or any application that supports ALSA mixer controls.
• Support for the HiFiBerry DSP add-on
• Connects directly to the Raspberry Pi, no additional cables needed
• No soldering, comes as a pre-fabricated kit
• Conforms to the Raspberry Pi hardware-attached-on-top (HAT) specification
• Compatible with all Raspberry Pi models with a 40-pin GPIO connector
• Directly powered from the Raspberry Pi, no additional power supply
• Three ultra-low-noise linear voltage regulators for optimal audio performance
• Low-jitter dual-domain clock for optimised clock decoupling from the Raspberry Pi
• Mic bias voltage for the use with electret microphones
• No anti-aliasing filter in the input path for best recording bandwidth
• HAT compliant, EEPROM for automatic configuration
• Gold plated RCA output connectors
• Comes with all components required to mount it. We include 4 M2.5x12mm spacers to fix the board onto the Raspberry Pi
