Mmini USB DAC Mini USB DAC Decoder PCM2704 USB Sound Card Analog DAC Decoder Board
Description
Mini PCM2704 USB sound card/DAC decoder board, size: 12*49MM (including terminal)
USB power supply, analog output. Plug directly into the USB port of the computer, eliminating the need for wiring
The main chip adopts BB's HIFI-level PCM2704 USB decoding chip. Its performance is better than the commonly used low-end chip CM102S series in the market. The power supply is USB power supply. The output end can be directly connected to earphones or as a pre-stage. The digital output can be more The advanced DAC decoder provides SPDIF digital signals to get better sound quality. Because it is an 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 single-chip digital-to-analog conversion chip. It has two digital-to-analog conversion output channels and an integrated USB interface controller. The interface complies with the USB1.1 standard. PCM2704 can receive 16-bit stereo or mono audio data with 48KHz, 44KHz and 32KHz sampling rates. The chip has integrated software volume and mute functions, which can simultaneously adjust the computer's volume and mute.
