Product introduction:
The main chip USESBBThe company'sHIFIlevelPCM2704 USB Decoding chip, its performance is better than that of the most commonly used low-end chips on the marketCM102SA series of , the power supply adoptsUSBPower supply, output can be directly connect headphones.Also can do before class.Digital output can be more advancedDAC decodersSPDIFDigital signal, in order to get a better sound quality.Because it is the external sound card, to avoid the serious electromagnetic interference inside the case.Signal to noise ratio and quality improved. PCM2704Is a monolithic analog-to-digital conversion chip. It has two analog-to-digital conversion output channel and one of integrationUSBInterface controller. InterfaceUSB1.1Standard.PCM2704You can receive48 KHZ.44 KHZand32 KHZThe sampling rate16A stereo or mono audio data, volume and mute function of internal integration chip, and can adjust the volume of the computer and synchronous mute. Technical parameters: The power supply voltage:5 V (USBThe power supply) The distortion degree of:THD + N: 0.006% (RL > 10 k Ω) The distortion degree of: THD + N: 0.025% (RL = 32 Ω) Signal to noise ratio: 98 dB Dynamic range: 98 dB Headphone output power: 12 mW (32 Ω RL =) USBSupport the sampling rate:16 bit and 32 k - 48 k
