Or external linear AC power supply, voltage range AC 7-15V.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"text-wrap-mode: nowrap;\"\u003eSupport 16BIT, 44-48K sampling rate, performance is better than PCM 27XX series.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"text-wrap-mode: nowrap;\"\u003eIt has a dedicated headphone output. The MOSFET output is used inside the chip, and it uses a floating ground wire. So there is no output capacitor. Connect headphones to get good bass.\u003cbr\u003eAnd its output current capability is very strong. Can drive almost all headphones. No headphone amplifier is required. It is recommended to use AC9-0 to switch to external power supply mode. There will be a great improvement.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"text-wrap-mode: nowrap;\"\u003eThis DAC supports 16-bit 44K or 48K digital sampling. Personally think it is enough. I have many chips with 24-bit 192K or 384K digital sampling. But there is no difference and meaning in actual application.\u003cbr\u003eCD discs are also 16-bit 44K samples. No one thinks that the sound quality of CDs is not good enough.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"text-wrap-mode: nowrap;\"\u003eThe greatest value and significance of the USB DAC is that it can use an external linear AC9-0 power supply. Plus ANSENMEI 7805 voltage regulator IC. You can get the same pure DC voltage as the battery.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"text-wrap-mode: nowrap;\"\u003eIt can avoid the noise generated by the internal switching power supply of the computer host or mobile phone notebook computer. Using an external power supply can achieve a better signal-to-noise ratio.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"text-wrap-mode: nowrap;\"\u003eIf you compare the parameters of the chip separately. Then the index of the integrated sound card is not worse than any external DAC in the world.\u003cbr\u003eThe main reason for the integrated sound card is that there is no way to use an external regulated power supply. Therefore, MINI USB DAC recommends using external power supply mode.\u003cbr\u003eYou can use a jumper to jump to the external power supply mode. The effect will be better.\u003cbr\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"text-wrap-mode: nowrap;\"\u003ePackage:\t\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"text-wrap-mode: nowrap;\"\u003e1*Mini USB Decoder\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Lilly Electronics","offers":[{"title":"Kit Without Shell","offer_id":40541242261633,"sku":"LJM-KIT-DAC-NO-CASE","price":21.0,"currency_code":"CAD","in_stock":true},{"title":"Finished Without Shell","offer_id":40541242294401,"sku":"LJM-DAC-NO-CASE","price":25.0,"currency_code":"CAD","in_stock":true},{"title":"Finished Product With Shell","offer_id":40541242327169,"sku":"LJM-DAC+CASE","price":30.0,"currency_code":"CAD","in_stock":true},{"title":"OTG Cable + TYPEC Plug","offer_id":40541242359937,"sku":"LJM-OTG+TYPE-C","price":11.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0578\/8647\/4369\/files\/f77fa5e0bf8d3c599ed0033205865140.jpg?v=1763013177","url":"https:\/\/www.lilly-electronics.com\/fr\/products\/mini-usb-dac-supports-mobile-phone-otg-usb-sound-card-with-mic-amp-diy","provider":"Lilly Electronics","version":"1.0","type":"link"}
