5V Mini PCM2704 USB DAC HIFI USB Sound Card USB Power DAC Decoder Board Module For Arduino Raspberry Pi 16 Bits

Mini PCM2704 USB sound card / DAC decoder board, size: 12 * 49MM (with terminal)

USB power supply, analog output directly plugged into the computer's USB port, eliminating the connection

The main chip uses BB's HIFI grade PCM2704 USB decoder chip, its performance is better than the market's most commonly used low-end chip CM102S series, power supply using USB power supply, the output can be directly connected headphones, but also do the pre-level. More advanced DAC decoders offer SPDIF digital signals for better sound quality. Due to the external sound card, it avoids serious electromagnetic interference in the chassis, and the signal-to-noise ratio and sound quality are improved.
PCM2704 is a monolithic analog-to-digital conversion chip. It has two digital-to-analog output channels and an integrated USB interface controller. The interface conforms to the USB 1.1 standard. PCM2704 can receive 48KHz, 44KHz and 32KHz sampling rate of 16-bit stereo or mono audio data, the chip integrated software volume and mute function, you can synchronize the adjustment of the computer volume and mute.

PCM2704 Parameters:

Supply voltage: 5 V (USB power),
Distortion: THD + N: 0.006 (RL> 10 kΩ)
Distortion: THD + N: 0.025 (RL = 32 Ω)
