1Pcs PCM2704 for USB DAC to S/PDIF Decoder Board Module Analog Output

Main chip HIFI level PCM2704 USB decoder chip, its performance is better than the low end of the market's most popular chip CM102S series, uses USB power supply, output can be directly connected to the headset, but also do pre-digital output for more advanced DAC decoder provides SPDIF digital signals to get better sound quality. because it is an external sound card, the chassis to avoid serious electromagnetic interference, signal to noise ratio and sound quality can be improved. PCM2704 is a monolithic digital-analog converter chip. It has two digital-analog converter output channel and an integrated USB interface controller. Interface complies with USB1.1 standard. PCM2704 can receive 48KHz, 44KHz and 32KHz sampling rate, 16-bit stereo or mono audio data integration software within the chip volume and mute function can be synchronized to adjust the volume and mute the computer. USB powered, analog output directly plugged into the computer on the USB port, eliminating the need to connect.
