5V Mini USB DAC Decoder PCM2704 USB Sound Card Analog DAC Decoder BoardPCM2704

Feature: 1. USB powered, analog output directly inserted into USB port of the computer, eliminating the need for connection. 2. Adopt HIFI level PCM2704 USB decoder chip, its performance is better than most commonly used CM102S series chip in the market. 3. 5V USB power supply, the output can be directly connected to the earphone. 4. Digital output can provide SPDIF digital signals for more advanced DAC decoders for better sound quality. 5. Since it is external sound card, serious electromagnetic interference in the chassis is avoided, and the signaltonoise ratio and sound quality are improved. 6. PCM2704 can receive 16bit stereo or mono audio data at 48KHz, 44KHz and 32KHz sampling rates. The chip integrates software volume and mute functions to synchronously adjust the volume and mute of the computer.
