The PAM8403 is a compact Class-D stereo audio amplifier module designed for high-quality audio reproduction in small spaces. It can be powered by a simple 5V DC input and supports a wide operating voltage range from 2.5V to 5.5V DC. This amplifier board produces 6W total output, with 3W per channel into a 4 Ohm load at 10% THD.
Key features include a maximum gain of 24 dB and a filterless architecture, simplifying design and reducing component count. The PAM8403 includes built-in short circuit protection and thermal protection, ensuring reliable operation. It is capable of driving 4 or 8 Ohm speakers directly, making it suitable for custom speaker projects. The module has stereo inputs for Left and Right channels with a common ground.
This amplifier board is ideal for applications requiring stereo audio amplification in a small form factor. Its efficient Class-D operation and lack of a required heatsink make it a versatile choice for various embedded audio systems and DIY projects.
