HiFiBerry DAC+ ADC Pro

The HiFiBerry DAC+ ADC Pro combines the well-know DAC+ Pro with an analogue input. Both input and output support sample rates up to 192kHz.

The HiFiBerry DAC+ ADC Pro is a high-resolution digital-to-analog and analog-to-digital converter for the Raspberry Pi (newer models with 40 pin GPIO connector). 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.

Specifications

• 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.
• Connects directly to the Raspberry Pi, no additional cables needed
• No soldering, comes as a pre-fabricated kit. You just plug it onto the Raspberry Pi, it is conform 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
• Audio input might require Linux kernel update (at least version 4.19.60)

Hardware

Note that the actual board might look a bit different. Layout and components might change without further notice. We do not guarantee a specific PCB layout or specific components.

Connectors and Jumpers

1. Analog input
2. Analog output
3. Analog output
4. I2S data
5. Microphone bias jumper (you need to close both jumpers to provide a microphone bias voltage)
6. Analog input

Note

You might need to update your Linux kernel to support the audio input features (at least Raspberry Pi kernel)
