The PAM8403 amplifier module is a versatile Class-D stereo audio amplifier designed for small board spaces. It can be powered by a simple 5V input and is capable of operating two 3W + 3W stereo speakers.
This module provides high-quality audio reproduction from a stereo input. Key electrical specifications include a wide operating voltage range from 2.5V to 5.5V DC, a maximum gain of 24 dB, and an output power of 3W+3W at 10% THD with a 4 Ohm load at 5V DC. It also features built-in short circuit protection and thermal protection, eliminating the need for a heatsink.
The PAM8403 is designed to drive 4 or 8 Ohm speakers directly, making it an excellent choice for custom speaker projects. The input section includes separate L (Left) and R (Right) channels with a common ground. Its filterless architecture simplifies design and reduces component count.
Applications for the PAM8403 include mini bass amplifiers, portable audio devices, and other projects requiring compact stereo amplification.
The PAM8403 amplifier module operates over a wide power supply range from 2.5V to 5.5V DC.
