PAM8403 Audio Amplifier With Volume Control The PAM8403 Audio Amplifier with Volume Control is a compact, high-efficiency stereo amplifier module designed for portable and embedded audio applications. It is built around the PAM8403 Class D amplifier chip, capable of delivering up to 3W per channel into 4Ω speakers at a 5V supply. The module features an integrated volume control potentiometer, which allows users to adjust audio levels easily and, in some designs, serves as a power switch when turned fully counter-clockwise. Operating within a voltage range of 2.5V to 5.5V, the module is well-suited for battery-powered devices, DIY audio projects, and smart electronics requiring high-quality sound in a small footprint. Its filter less design and built-in protections make it a reliable choice for various applications. Features: High Efficiency Up to 90% efficiency with low quiescent current. Filterless Design Directly drives speakers without LC filters. Volume Control Integrated potentiometer for easy audio level adjustment. Wide Voltage Range Operates at 2.5V–5.5V Dc. Protection Features Short-circuit and thermal shutdown protection. Specifications: Parameter Value Operating Voltage 2.5V to 5.5V Output Power 3W per channel into 4Ω at 5V Efficiency Up to 90% Speaker Impedance 4Ω to 8Ω Dimensions 29mm x 20mm x 16mm (including potentiometer) Weight Approximately 5g (varies by manufacturer) Amplifier Type Class D Total Harmonic Distortion + Noise (THD+N) Low, ensuring high-quality audio Protection Features Short-circuit, thermal, under-voltage lockout Note: Input audio should be via shielded wire for best performance. Use a proper filtered power supply with good filter capacitors. Take care not to short speaker wires else IC will get damaged. Make sure the power supply never exceeds 5.5V else IC will get damaged. Use a regulated power supply.
