PAM8304AYR DIODES Audio

The PAM8304AYR from Diodes Incorporated is a high-efficiency mono Class-D audio amplifier delivering up to 3W into a 4Ω speaker. For selection, its standout advantage is filterless operation, which eliminates the need for bulky external LC filters, reducing cost and PCB area. The wide 2.8V to 6V supply range accommodates single-cell Li-Ion batteries or 5V USB power rails. Key features include depop circuitry to minimize turn-on/off transients, short-circuit protection, and thermal shutdown for robust reliability. Its high efficiency (typically >85%) significantly extends battery life. In application, it excels in portable Bluetooth speakers, tablets, smartphones, GPS navigators, and handheld gaming devices. The tiny DFN3030-8 package makes it ideal for space-constrained wearables and IoT audio alert systems, while its overall low component count simplifies design and accelerates time-to-market for compact consumer audio products.
