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 8Ohm speaker at over half a Watt) - making it perfect for portable and battery-.The 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 a high frequency 250KHz square wave PWM that is then 'averaged out' by the speaker coil - the high frequencies are not heard.\u003c\/p\u003e","brand":"Shop2IndiaBei","offers":[{"title":"Default Title","offer_id":43035493040296,"sku":"U2I-1-324018204245","price":1290.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0300\/1588\/1354\/products\/128472-6__05610.jpg?v=1672650334","url":"https:\/\/shop2india.com\/products\/pam8302-2-5w-class-d-mono-digital-audio-amplifier-power-amp-board-volume-ad-p7r6","provider":"SHOP2INDIA GATEWAY","version":"1.0","type":"link"}
