PCM5122 DAC Board for Raspberry Pi Burr Brown 24bit 192kHz
The HiFiBerry DAC2 Pro is a high resolution digital to analog and analog to digital converter, dedicated to be used in combination with a Raspberry Pi (A+, B+, 2B, 3B, 3B+, 4B+, Zero). It is a sound card for Raspberry Pi optimized to enjoy high quality audio playback at a low price.
It is based on a Burr Brown conversion chip supporting sampling rates up to 24bit 192kHz PCM. It also embeds a low jitter clock circuit and integrates a headphone amplifier.
The input is on a 40 pin GPIO header and the output is on stereo RCA (line) or via the amplified 3.5mm headphone output. There is also an additional analog output on a PCB connector. Another PCB connector allows to connect a DSP module to the DAC2 Pro.
