دیتاشیت برد RasPi IQaudio DAC plus
Description:
IQaudio DAC+ is an audio output HAT for all generations of Raspberry Pi from Raspberry Pi 1 Model B+ onwards, and supports 24‑bit 192kHz high-resolution digital audio. It uses the Texas Instruments PCM5122 DAC to deliver stereo analogue audio to a pair of phono connectors, and also supports a dedicated headphone amplifier.
IQaudIO DAC Pro is based on a Burr Brown PCM5242 32-bit / 384 kHz converter , allowing for Full HD 24-bit / 192 kHz audio playback. The module is equipped with two RCA connectors, a mini jack connector and supports balanced / differential output for XLR. The communication overlay uses an I2S interface to reduce the load on the Raspberry Pi processor. IQaudIO has been taken over by the Raspberry Pi Foundation, providing ongoing support to Raspberry Pi users.
