It offers low THD+N, allowing it to achieve high-quality sound reproduction. The new filterless architecture allows the device to drive the speaker directly, requiring no low-pass output filters, thus saving system cost and PCB area.\u003c\/p\u003e\n\u003cp\u003eWith the same numbers of external components, the efficiency of the PAM8403 is much better than that of Class-AB cousins. This 5v audio amplifier board can extend the battery life, which makes it well-suited for portable applications.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eFeatures :\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDual channel stereo, high output power (3 w + 3 w power @ 5V and 4 ohms load).\u003c\/li\u003e\n\u003cli\u003eGood sound quality.\u003c\/li\u003e\n\u003cli\u003eDouble panel wiring solves crosstalk.\u003c\/li\u003e\n\u003cli\u003eSuper mini design allows it to be easily placed in a variety of digital products.\u003c\/li\u003e\n\u003cli\u003e3W Output at 10% THD with a 4ΩLoad and 5V Power Supply.\u003c\/li\u003e\n\u003cli\u003eFilterless, Low Quiescent Current and Low EMI.\u003c\/li\u003e\n\u003cli\u003eSuperior Low Noise.\u003c\/li\u003e\n\u003cli\u003eShort Circuit Protection.\u003c\/li\u003e\n\u003cli\u003eThermal Shutdown\u003c\/li\u003e\n\u003cli\u003eInput audio should be via shielded wire\u003c\/li\u003e\n\u003cli\u003ebig output power, sound quality is good.\u003c\/li\u003e\n\u003cli\u003eUnique without LC filter class D digital power board\u003c\/li\u003e\n\u003cli\u003ecan use computer USB power supply directly\u003c\/li\u003e\n\u003cli\u003ehigh amplification efficiency\u003c\/li\u003e\n\u003cli\u003emade with solid plate welding machine\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003eSpecifications:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eAmplifier IC: PAM 8403\u003c\/li\u003e\n\u003cli\u003eOperating Voltage Range: 2.5V – 5.5V\u003c\/li\u003e\n\u003cli\u003eMax Gain: 24 dB\u003c\/li\u003e\n\u003cli\u003eCurrent Handling Capacity: 8 mA\u003c\/li\u003e\n\u003cli\u003eEfficiency: 0.87\u003c\/li\u003e\n\u003cli\u003eS\/N Ratio: 80 dB\u003c\/li\u003e\n\u003cli\u003ePower supply Rejection ratio: -58 dB\u003c\/li\u003e\n\u003cli\u003eLoad: Can direct drive 4 or 8 ohm small speakers\u003c\/li\u003e\n\u003cli\u003eDimensions in mm (LxWxH): 21.1 x 18.5 x 3\u003c\/li\u003e\n\u003cli\u003eWeight (gm): 5\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003eApplication :\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBluetooth Stereo Audio hands-free\/headsets\u003c\/li\u003e\n\u003cli\u003eIn robots that speak or generate sounds to indicate activities\u003c\/li\u003e\n\u003cli\u003ePortable Speakers\u003c\/li\u003e\n\u003cli\u003eLCD Monitors \/ TV Projectors\u003c\/li\u003e\n\u003cli\u003eArduino or Raspberry Pi Game Machines\u003c\/li\u003e\n\u003cli\u003eSpeaker Phones\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003ePackage Includes :\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e1 x PAM8403 Amplifier Board 3W Digital power\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"eBhoot Electronics","offers":[{"title":"Default Title","offer_id":43465991225462,"sku":null,"price":14.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0697\/7345\/9574\/files\/Untitled_design_-_2022-10-01T111526.210.png?v=1780229395","url":"https:\/\/ebhoot.com\/products\/pam8403-5v-two-channel-stereo-audio-amplifier-module","provider":"eBhoot Electronics","version":"1.0","type":"link"}
