Product Introduction

Raspberry pie special HIFI DAC + + V2.0 PCM5122 pifi DAC chip sound card I2S interface

Function Description:

1. Upgrade DAC chip, adopt THE higher-end PCM5122 chip of BB company (acquired by TI Company), adopt I2S interface, and adjust the volume and audio parameters through I2C interface;Support 16-bit to 32-bit audio data format;Both distortion and dynamic are ideal, supporting a high 384kHz sampling rate, a dynamic range of 112dB, and a distortion of -93dB.Soft rising or falling oblique waves and simulated noise for operation with 120dB SNR (static to noise ratio) without knock.

2. PCM5122 has the same integrated negative charge pump, and the output does not need to be separated by dc capacity;2.1 Output of Vrms ground center;Very good ability to suppress out-of-band noise.By supporting as low as 1 k Ω load, PCM510xA can drive multiple products in parallel.(that is, multiple amplifiers used at the same time).

3. Gold-plated RCV double terminals and gold-plated 3.5mm headphone holder are adopted for the output port

4. Isolated power supply design is adopted to isolate the raspberry PI power supply from the independent power supply of DAC, and the magnetic beads are used for mutual non-interference to get rid of the current sound

5. Welding is free. It can be used by directly plugging into the expansion board, and I2S interface is adopted to directly decode digital to analog, and DAC mode is not a USB interface.

6. Add dual-color LED to provide status display, red light is DAC power indicator (power is normally on), green light is DAC working status light (on when decoding, off when stopping or not working), so as to better understand the working condition of DAC

7. It is perfectly compatible with the size of raspberry PI HAT. The PCB board adopts high gilding process and curved routing (high-end HIFI DAC adopts curved routing) to better guarantee the impedance continuity of signals and reduce signal reflection and refraction.
