The \u003cb data-path-to-node=\"7\" data-index-in-node=\"48\"\u003ePAM8302A Mono Class D Amplifier\u003c\/b\u003e is engineered to deliver a massive audio upgrade to your custom electronics. Whether you are building a portable retro gaming console, a smart home alert system, or an interactive STEM project, this module effortlessly drives up to 2.5 Watts into 4-8 ohm impedance speakers.\u003c\/p\u003e\n\u003cp data-path-to-node=\"7\"\u003e \u003c\/p\u003e\n\u003ch3 data-path-to-node=\"8\"\u003eHigh Efficiency for Battery-Powered Builds\u003c\/h3\u003e\n\u003cp data-path-to-node=\"9\"\u003ePower management is critical in portable electronics. Because this module utilizes a \u003cb data-path-to-node=\"9\" data-index-in-node=\"85\"\u003eClass D controller\u003c\/b\u003e, it boasts an incredible \u003cb data-path-to-node=\"9\" data-index-in-node=\"129\"\u003e90%+ power efficiency\u003c\/b\u003e when driving an 8Ω speaker at over half a Watt. It sips power from a standard 2.0V-5.5VDC supply, meaning your battery life lasts significantly longer compared to traditional Class AB amplifiers.\u003c\/p\u003e\n\u003cp data-path-to-node=\"9\"\u003e \u003c\/p\u003e\n\u003ch3 data-path-to-node=\"10\"\u003eBuilt-in Protection \u0026amp; Precision Volume Control\u003c\/h3\u003e\n\u003cp data-path-to-node=\"11\"\u003eSafety and stability are built right into the board. The PAM8302A features robust \u003cb data-path-to-node=\"11\" data-index-in-node=\"82\"\u003ethermal and over-current protection\u003c\/b\u003e, ensuring your circuits remain safe even during peak audio spikes. Additionally, the onboard volume trim potentiometer gives you precise control, allowing you to easily adjust the output down from the default 24dB gain to perfectly match your project's acoustic needs.\u003c\/p\u003e\n\u003cp data-path-to-node=\"11\"\u003e \u003c\/p\u003e\n\u003ch3 data-path-to-node=\"12\"\u003eBridge-Tied Output for Direct Speaker Drive\u003c\/h3\u003e\n\u003cp data-path-to-node=\"13\"\u003eDesigned for simplicity and signal integrity, the output of this module is \u003cb data-path-to-node=\"13\" data-index-in-node=\"75\"\u003e\"Bridge Tied.\"\u003c\/b\u003e This means the output pins connect directly to your speaker coils without needing a ground connection. The high-frequency 250KHz square wave PWM is mechanically averaged out by the speaker itself, ensuring you only hear crisp, clear audio. \u003ci data-path-to-node=\"13\" data-index-in-node=\"330\"\u003e(Note: Because of this architecture, this module must drive speakers directly and cannot be chained into another amplifier).\u003c\/i\u003e\u003c\/p\u003e","brand":"Sun Cheong Computer Company Limited","offers":[{"title":"Default Title","offer_id":46945685569687,"sku":"21PS001589","price":119.0,"currency_code":"TWD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0440\/4022\/4919\/files\/pam8302a-class-d-amplifier-top-view.jpg?v=1772168810","url":"https:\/\/scccltd.com\/en-tw\/products\/pam8302a-2-5w-class-d-audio-amplifier-module","provider":"Sun Cheong Computer Company Limited","version":"1.0","type":"link"}
