The HiFiBerry DAC2 ADC Pro is a high-resolution digital-to-analog and analog-to-digital converter for the Raspberry Pi, which combines our well-known DAC2 Pro with an analogue input. Both input and output support sample rates up to 192kHz. It is our first DAC/ADC board that also supports our DSP add-on. This is a special sound card for the Raspberry Pi, optimised for one specific use case: the best audio playback and recording quality! It is specifically designed for applications that do not only need playback, but also recording functionalities. 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 and ADC. You can control the input and output parameters using “alsamixer” or any application that supports ALSA mixer controls. * Support for the HiFiBerry DSP add-on * Connects directly to the Raspberry Pi, no additional cables needed * No soldering, comes as a pre-fabricated kit * 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 * Low-jitter dual-domain clock for optimised clock decoupling from the Raspberry Pi * Mic bias voltage for the use with electret microphones * No anti-aliasing filter in the input path for best recording bandwidth * 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 Specifications Maximum input voltage 2.1Vrms 4.2Vrms for balanced input Maximum output voltage 2.1Vrms ADC signal-to-noise ratio 110db typical DAC signal-to-noise ratio 112db typical ADC THD+N -90db typical DAC THD+N -93db typical Frequency response 10Hz-70kHz (-3dB) Input gain -12db to 32dB Power consumption <0.3W Sample rates 44.1-192kHz Resources * HiFiBerry DAC2 ADC Pro Datasheet * 3D model (step) * Overlay for config.txt: dtoverlay=hifiberry-dacplusadcpro Package Contents * 1x HiFiBerry DAC2 ADC Pro * 1x Mounting fixing pack https://elecena.pl/product/26816337/hifiberry-dac2-adc-pro 2024-08-21 https://elecena.pl/product/26816337/hifiberry-dac2-adc-pro 2024-09-18 https://elecena.pl/product/26816337/hifiberry-dac2-adc-pro 2024-10-09 https://elecena.pl/product/26816337/hifiberry-dac2-adc-pro 2024-11-29 https://elecena.pl/product/26816337/hifiberry-dac2-adc-pro 2024-11-30 https://elecena.pl/product/26816337/hifiberry-dac2-adc-pro 2025-07-11 https://elecena.pl/product/26816337/hifiberry-dac2-adc-pro 2025-11-28 https://elecena.pl/product/26816337/hifiberry-dac2-adc-pro 2025-11-29
