Inside the miniature chip is a class D controller, able to run from 2.0V-5.5VDC. Since the amp is a class D, its very efficient (over 90% efficient when driving an 8 speaker at over half a Watt) - making it perfect for portable and battery-powered projects. It has built in thermal and over-current but we could barely tell it got hot. There's even a volume trim pot so you can adjust the volume on the board down from the default 24dB gain. This board is a welcome upgrade to basic \"LM386\" amps!\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan style=\"font-size:16.0px;\"\u003eThe A+ and A- inputs of the amplifier go through 1.0uF capacitors, so they are fully 'differential' - if you don't have differential outputs, simply tie the Audio- pin  to ground. The output is \"Bridge Tied\" - that means the output pins connect directly to the speaker pins, no connection to ground. The output is a high frequency 250KHz square wave PWM that is then 'averaged out' by the speaker coil - the high frequencies are not heard. All the above means that you can't connect the output into another amplifier, it should drive the speakers directly.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan style=\"font-size:16.0px;\"\u003eComes with a fully assembled and tested breakout board. We also include header to plug it into a breadboard and a 3.5mm screw-terminal blocks so you can easily attach\/detach your speaker. You will be ready to rock in 15 minutes! Speaker is not included, use any 4 ohm or greater impedance speaker.\u003c\/span\u003e\n\u003c\/h2\u003e\n\u003cdiv\u003e\u003cul\u003e\n\u003cli\u003e\u003cspan style=\"font-size:14.0px;\"\u003eOutput Power: 2.5W at 4, 10% THD, 1.5W at 8, 10% THD, with 5.5V Supply\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-size:14.0px;\"\u003e50dB PSRR at 1KHz\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-size:14.0px;\"\u003eFilterless design, with ferrite bead + capacitors on output.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-size:14.0px;\"\u003eFixed 24dB gain, onboard trim potentiometer for adjusting input volume.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-size:14.0px;\"\u003eThermal and short-circuit\/over-current\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-size:14.0px;\"\u003eLow current draw: 4mA quiescent and 1uA in shutdown mode\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/div\u003e\n\u003c\/div\u003e\u003c\/div\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"aeProduct.getSubject()\" src=\"https:\/\/ae01.alicdn.com\/kf\/S982d50129ece4a898987de42e56d8760o.jpg\" width=\"600\" data-src=\"https:\/\/ae01.alicdn.com\/kf\/S982d50129ece4a898987de42e56d8760o.jpg\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"aeProduct.getSubject()\" src=\"https:\/\/ae01.alicdn.com\/kf\/S5325ae1de0244da9b02f6f0da4d07821U.jpg\" width=\"600\" data-src=\"https:\/\/ae01.alicdn.com\/kf\/S5325ae1de0244da9b02f6f0da4d07821U.jpg\"\u003e\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/div\u003e\r\n","brand":"Yoeruyo","offers":[{"title":"Default Title","offer_id":55374650573099,"sku":"\u003cnone\u003e","price":5.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1000\/5744\/8747\/files\/Sf5750f737d1348ecaea6b1f95d67632eo.webp?v=1788326230","url":"https:\/\/yoeruyo.com\/products\/2130-mono-2-5w-class-d-audio-amplifier-pam8302-module-mono-2-5w-class-d-audio-amplifier-pam8302","provider":"Yoeruyo","version":"1.0","type":"link"}
