When pin “SHDN” is Low (0V), the amplifier’s bias circuit will be closed, then the module goes into sleep mode, while when pin “SHDN” is High (5V), the working mode enables. The audio stereo amplifier is in working mode by default (the pin is unconnected).\u003c\/p\u003e\n\u003cp\u003eThis Mini Audio Stereo Amplifier can be used in robot voice systems, DIY music boxes and sound modification.\u003c\/p\u003e\n\u003ch2\u003eNotes:\u003c\/h2\u003e\n\u003col\u003e\n\u003cli\u003eDo not connect the positive and negative poles in reverse.\u003c\/li\u003e\n\u003cli\u003eThe negative poles for the high and low channels are independent, do not connect them together.\u003c\/li\u003e\n\u003cli\u003eThe power supply should be no more than 5.5V, voltage higher than this will damage the IC.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003ch2\u003eSPECIFICATION\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Input:\u003c\/strong\u003e DC 3.3-5.5V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower:\u003c\/strong\u003e 3W（4Ω，5V）\u003c\/li\u003e\n\u003cli\u003eClass D amplifier\u003c\/li\u003e\n\u003cli\u003eSupport left and right channels\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEfficiency:\u003c\/strong\u003e \u0026gt;90%\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimension:\u003c\/strong\u003e 18x20mm\/0.71 x0.79”\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePin Pitch:\u003c\/strong\u003e 2.54mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eDOCUMENTS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/wiki.dfrobot.com\/3W_mini_audio_stereo_amplifier__SKU_DFR0119_\" target=\"_blank\"\u003eProduct wiki\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/image.dfrobot.com\/image\/data\/DFR0119\/pam8403.pdf\" target=\"_blank\"\u003ePAM8403 Datasheet\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DFRobot","offers":[{"title":"Default Title","offer_id":39287570497619,"sku":"DFR0119-O","price":4.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0174\/1800\/products\/DFR0119-O.jpg?v=1616427712","url":"https:\/\/shop.pimoroni.com\/en-eu\/products\/fermion-3w-mini-audio-stereo-amplifier-w2-54","provider":"Pimoroni Ltd","version":"1.0","type":"link"}
