DAC Board with DSP for Raspberry Pi Burr Brown 24bit 192kHz
The HiFiBerry DAC+ DSP combines both a digital to analog converter based on a Burr Brown DAC chip - with a digital input and output, as well as an analog output - and a powerful 300MHz DSP processor. The latter, working with SigmaStudioStereo, will allow you to adapt the sound reproduction of the module to your listening and your equipment. It has been designed to work with a Raspberry Pi, with a 40 pins GPIO input.
1 | Analog DSP input |
2 | External I2S DAC output |
3 | Selfboot |
4 | Digital DSP inputs and outputs |
5 | Optical Toslink input (up to 96kHz) |
6 | Optical Toslink output (up to 192kHz) |
7 | RCA Output |
The analog inputs allow a direct connection to the DSP. However, it is not an ADC. The inputs are designed to use an external analog controller as variable resistors to control a DSP program. It is therefore necessary to create your own DSP program to use this function.
GND | 1 | 2 | Power supply +3.3V (up to 0.1A) |
AUX ADC1 | 3 | 4 | AUX ADC0 |
AUX ADC3 | 5 | 6 | AUX ADC2 |
This output provides the I2S digital data stream that is used by the built-in DAC.

Raspberry Pi SDA | 3 | 4 | Raspberry Pi SCL |
I2S BCLK | 5 | 6 | I2S DATA |
I2S LRCLK | 7 | 8 | MCLK |
This connector gives access to additional I2S inputs and outputs of the DSP.
