Description: <br> <br>This item is clude Pifi DAC + PCM5122 DAC, I2S interface, analogue output signal, Compatible with for Raspberry Pi B + a + 2B Raspberry Pi 3B (64-bit). <br> <br> <br>Features: <br> <br> Pifi DAC + PCM5122 DAC, I2S interface, analogue output signal, Compatible with for Raspberry Pi B + a + 2B Raspberry Pi 3B (64-bit). <br> <br>PCM5122 also integrated negative charge pump, the output without DC blocking capacitor; 2.1 Vrms ground center output; ability to suppress very good band noise. Due to the load support low to 1K, PCM510xA can drive a multitude of parallel products. <br> <br>Gold-plated RCV Double Clamp and gold-plated 3.5 mm jack socket (Recommended via Amplifier). <br>The insulated power supply design, make the raspberry pie nutrition and DAC part of the independent power supply isolation, and by the bead completely without mutual interference, get rid of the current sound. <br>Increase for double color LED provides state display, red for DAC power indicator (power normal bright), the green light for the condition of DAC lamp (decoding and bright, stop or does not work out), better understanding of DAC work. <br> <br>Perfect compatibility raspberry pie official PI HAT size, gold plating process of tall based on circuit board, arc wire (high-end HIFI DAC adopts arc wire), better guarantee the impedance of the signal continuity, reduce the signal reflection and refraction. <br>Provided with an infrared receiver interface. <br> <br>Specification: <br>Condiiton: 100% Brand New <br> <br>Sampling Frequency:384KHz <br>- Resolution (Bits) :16-32 <br>- Digital Audio Interface :I2S <br>- SNR :120dB <br>- THD:-93dB <br>- Dynamic range :112dB <br>- Supports for Raspberry Pi B+, Raspberry Pi 2 Model B,Raspberry Pi 3B (64-bit) <br> <br> <br>Package Included: <br> <br>1 x Digital Audio Card for Raspberry PI <br> <br>1 x HIFI DAC for Raspberry PI <br> <br> <br> <br>Notice: <br>Please allow 1-3cm error due to manual measurement and make sure you do not mind before ordering. <br>Please understand that colors may exist chromatic aberration as the different placement of pictures.1、Upgrade DAC chip, using PCM5122 chip of high end, using I2S interface, and can via the i2c interface adjust audio volume parameter adjustment; supports 16 32 bit audio data format; Distortion and dynamic is very ideal, support the tall sampling rate of 3 <br>2、PCM5122 also integrated negative charge pump, the output without DC blocking capacitor; 2.1 Vrms ground center output; ability to suppress very good band noise. Due to the load support low to 1K, PCM510xA can drive a multitude of parallel products. <br>3、Output ports with gold plated HS dual terminal and gold-plated 3.5mm Headset seat. <br>4、The insulated power supply design, make the raspberry pie nutrition and DAC part of the independent power supply isolation, and by the bead completely without mutual interference, get rid of the current sound. <br>5、Perfect compatibility raspberry pie official PI HAT size, gold plating process of tall based on circuit board, arc wire (high-end HIFI DAC adopts arc wire), better guarantee the impedance of the signal continuity, reduce the signal reflection and refract
