Original pie zero pi B + /2B /3B dedicated HIFI DAC+ sound card I2 | Электронные компоненты и принадлежности

Features:

1.    Upgrade DAC chip,UseBBThe company(Has beenTICompany acquisition) MoreHigh endOfPCM5122Chip, usedI2SInterface, and can be through the I2C interface for volume and audio parameter adjustment;16To32Bit audio data format; distortion and dynamic are very ideal, support tall384kHzOf the sampling rate, dynamic range112dBDistortion-93DbThe For the operation with no detonation120dBNoise margin(SNR)Soft rise or fall ramp and simulated squelch.

2.    PCM5122 the sameIntegrated negative charge pump, the output without DC blocking capacitor; 2.1VrmsGround center output; very good ability to suppress out-of-band noise1kOf the loadPCM510xAAble to drive multiple parallel products(That is, multiple amplifiers used at the same time).

3.    The output port is gold platedRCVDouble terminal and gold plated3.5mmHeadset

4.    The use of isolated power supply design, so that raspberry power supply andDACPart of the independent power supply isolation, and through the magnetic beads are not interfere with each other, get rid of the current sound

5.    Free welding, plug directly into the expansion board can be used,AndUseI2SInterface direct decode digital to analog, nonUSBInterfaceDAC mode,

6.Increase the status of the display for the two-color led, red light for the DAC power indicator (power is normal), the green light for the DAC working status light (working decoding on, stop or not work off), a better understanding Of the work of the DAC

7.    Perfectly compatible with raspberry official PI HAT size,PCBThe board uses a high gold-plated process, arc traces (high-end HIFI DAC are used arc alignment), better to ensure the signal critical continuity, reduce signal reflection and refraction.
