PCM2704 USB Sound Card PCM2704 16 Bits Mini USB DAC Decoder For Arduino Pi 16 Bits _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ Mini USB decoder module:Mini PCM2704 USB Sound Card /DAC Decoding Board,USB power supply, analog output. It plugs directly into the USB port of the computer, eliminating the need to connect._x000D_ The main chip adopts Hifi-level PCM2704 USB decoding chip, whose performance is better than the most commonly used low-end chip CM102S series on the market. The power supply is USB, and the output end can be directly connected to the headset or the front stage. _x000D_ The digital output feeds the SPDIF digital signal to more advanced DAC decoders for better sound quality. Due to the external sound card, avoid serious electromagnetic interference in the case, signal-to-noise ratio and sound quality can be improved._x000D_ 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. This interface complies with USB1.1 standards. _x000D_ The PCM2704 can receive 16-bit stereo or mono audio data with sampling rates of 48KHz, 44KHz and 32KHz. The integrated software volume and mute function can synchronously adjust the volume and mute of the computer._x000D_ _x000D_ Power supply voltage: 5 V (USB)_x000D_ Distortion: THD+N: 0.006% (RL Greater than 10 k)_x000D_ Distortion: THD+N: 0.025% (RL = 32)_x000D_ Signal to noise ratio: 98 dB_x000D_ Dynamic range: 98 dB_x000D_ Earphone output power: 12 mW (RL = 32 )_x000D_ USB supports sampling rate: 16BIT/32-48KHZ_x000D_ USB system support: for WINXP/WIN7/WIN8, for MAC OS 9/OS X/for Android 4.0 or above (OTG-enabled models required)_x000D_ Colour:As Shown_x000D_ Material:Metal+Plastic_x000D_ _x000D_ Package Contents:_x000D_ 1 x DAC decoding board Module_x000D_ _x000D_ Only the above package content, other products are not included._x000D_ Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
