Raspberry Pi Lossless Analog Audio Board 32bit HiFi DAC Audio Card Expansion Board for Raspberry Pi 4B/3B+ (with Acrylic Case)

* * -- This is a special HIFI DAC expansion board designed for the Raspberry pi 4B/3B+ ,using TI's DAC chip (PCM5122), using an I2S interface.The user can use this expansion board with audio playback systems (eg: volumio, xbmc system etc.) to build its own network HIFI player.
* - * -- HiFi DAC audio card expansion board adopts the higher-end PCM5122 chip, adopts 25 interface and can adjust the volume and audio parameters through the 12C interface.Supports 16 to 32-bit audio data format; distortion and dynamics are very ideas.Support high 384kHz sampling rate, dynamic range 112dB, distortion -93Db. 120dB squelch signal-to-noise ratio (SNR) for soft up or down ramps and analog squelch with no pops operation.
* -- * -- PCM5122 also integrates a negative charge pump, and the output does not need a DC blocking capacitor. 2.1vrms grounded center output; very good ability to suppress out-of-band noise.
* * -- The isolated power supply design is adopted to isolate the Raspberry Pi power supply from the DAC part of the independent power supply, and the common ground of the magnetic beads does not interfere with each other, so as to get rid of the current noise.
* * -- This raspberry pi analog audio board can be used directly by plugging in the expansion board, and the I25 interface is used to directly decode the digital to analog non-USB interface DAC method.The output port adopts gold-plated RCV dual terminals and gold-plated 35mm headphone jack.
