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. With the same numbers of external components, the efficiency of the PAM8403 is much better than that of Class-AB cousins.\u003c\/p\u003e\n\u003cp\u003eThe \u003cspan\u003ePAM8403 \u003c\/span\u003e\u003cspan\u003eaudio amplifire\u003c\/span\u003e can extend the battery life, which makes it well-suited for portable applications. The board uses the typical circuit design of PAM8403, using MICRO USB power supply (reserved wire power interface), it is easy to use a universal mobile phone charger for its power supply, resistance devices are standardized patch technology, simple and stable.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e3W Output at 10% THD with a 4Ω Load 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\u003eEfficiency up to 90% \u003c\/li\u003e\n\u003cli\u003eShort Circuit Protection \u003c\/li\u003e\n\u003cli\u003eIt is designed for Bluetooth audio receiver module dedicated interface.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"INDIAN HOBBY CENTER","offers":[{"title":"Default Title","offer_id":43845452562475,"sku":null,"price":49.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0574\/6796\/1387\/files\/1_1000x_6f4138c8-01bf-40c8-8c36-3fd7e4fb9b8f.png?v=1774875291","url":"https:\/\/www.indianhobbycenter.com\/products\/5v-dc-mini-class-d-pam8403-usb-power-amplifier-board","provider":"Indian Hobby Center","version":"1.0","type":"link"}
