HiFiBerry DAC+ ADC
The HiFiBerry DAC+ ADC is a high-resolution digital-to-analog converter for the Raspberry Pi (newer
models with 40 pin GPIO connector). It is specifically designed for applications that need not only
playback, but also recording functionalities.
Features
• Stereo input and output
• Dedicated 192kHz/24bit high-quality Burr-Brown DAC
• Hardware volume control for DAC. You can control the output volume using “alsamixer” or any
application that supports ALSA mixer controls.
• Balanced input supported with optional XLR connectors
• 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 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
• 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
Dimensions without package 5.5 x 6.5 x 2 cm
Dimensions including package 9.5 x 7.5 x 2.5 cm
Weight 0.02 kg
GTIN 4260439550583
Use Recommendations
• Music playback on the Raspberry Pi
• Connect devices such as mobile phones, MP3 players, Amazon Alexa, or other gear.
• Music processing (connect synthesizer and process audio on the Pi)
• Karaoke devices
