HiFiBerry DAC+ ADC

The HiFiBerry DAC+ ADC is a high-resolution digital-to-analogue and analogue-to-digital converter for the Raspberry Pi, that combines the well-known DAC+ with an analogue input. Both input and output support sample rates up to 192kHz.

This is a special sound card for the Raspberry Pi, optimised for one specific use case: the best audio playback quality! It is specifically designed for applications that not only need playback but also recording functionalities. We also stock a Pro model and a 60W Class-D Amplifier add-on! 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. You can control the output volume 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 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

* 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 requires updated Linux kernel
