The HiFiBerry DAC+ ADC Pro combines the well-known DAC+ Pro with an analogue input. Both input and output support sample rates up to 192kHz. It's is a high-resolution digital-to-analogue and analogue-to-digital converter for the Raspberry Pi (newer models with 40 pin GPIO connector). Note: This board will not fit inside the HighPi case range due to the headphone connector. The Pro model is an upgrade of the standard version with the following features * 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 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. 60W Class-D Amplifier add-on now available! 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. * Connects directly to the Raspberry Pi, no additional cables needed * No soldering - Comes as a pre-fabricated kit. * 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 * Pro: Low-jitter dual-domain clock for optimised clock decoupling from the Raspberry Pi * Pro: Mic bias voltage for the use with electret microphones * Pro: 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 Balanced/un-balanced input connector J4 This 6-pin connector can be used to connect a balanced input (e.g. XLR or 6.5mm jacks). Pin 1 is on the left bottom corner. in R- 1 2 in R+ GND 3 4 GND in L+ 5 6 in L- Output connector P5 This connector can be used to connect to external components, e.g. an amplifier. The output is connected in parallel to the RCA jacks. Pin 1 is on the top left. +5V 1 2 R GND 3 4 GND +5V 5 6 L Configuration To support the DAC+ ADC, a Raspberry Pi Linux kernel of at least version 4.19.60 is required. Have a look at the documentation on how to update the Linux kernel. Overlay for config.txt: dtoverlay=hifiberry-dacplusadcpro If you’re still using an older Linux kernel that does not support the DAC+ ADC, you can still use the output-part of the DAC+ ADC using the HiFiBerry DAC+ driver: dtoverlay=hifiberry-dacplus Resources * Datasheet * Updating the Linux kernel * Use dynamic microphones * 3D model (step) Notes * You may need to update your Linux kernel to support the audio input features (at least Raspberry Pi kernel 4.19.60) * Note that the actual board received might look different from the images. Layout and components may change without notice. HiFiBerry does not guarantee a specific PCB layout or specific components.
