HiFiBerry DAC2 HD Digital to Analogue Converter for Raspberry Pi

The HiFiBerry DAC2 HD is a premium-grade digital-to-analogue converter (DAC) designed specifically for use with Raspberry Pi models featuring a 40-pin GPIO connector. Engineered for audio enthusiasts, it provides a simple, high-fidelity upgrade path for your Raspberry Pi, transforming it into a capable high-quality audio source without the need for complex setup or additional power supplies.

Installation is remarkably straightforward. The DAC board is a 'HAT' (Hardware Attached on Top) that connects directly to the GPIO header of your Raspberry Pi, requiring no soldering, extra cables, or an external power adapter. It draws all necessary power directly from the Pi itself, ensuring a clean and minimalist setup.

Key Audio Features

At the heart of the DAC2 HD is a dedicated Burr-Brown DAC chip, capable of handling high-resolution audio up to 192kHz/24-bit. This is paired with a custom current-to-voltage output stage that incorporates high-end filtering for exceptionally clear and accurate sound reproduction.

To preserve audio purity, the board utilises ultra-low-noise linear voltage regulators, minimising electrical interference that can degrade sound quality. A dedicated low-jitter clock further optimises timing performance, ensuring precise digital-to-analogue conversion. For user control, it features hardware volume control managed directly through the DAC chip.

Physical Connectivity

Audio output is provided via gold-plated stereo RCA connectors, offering a reliable and high-quality connection to your amplifier or active speakers. The compact form factor is designed to sit neatly on top of your Raspberry Pi.

Compatibility & Requirements

This DAC HAT is compatible with all Raspberry Pi models that have a 40-pin GPIO header, including the Raspberry Pi 3, 4, and 5. Please note that it requires a minimum of Linux kernel 4.19.97 or newer for
