PAM8403 Dual Channel Stereo Digital Audio Amplifier Module is a 3W per channel, dual channel stereo, Class D digital amplifier, which is based on the PAM8403 integrated chip. It can reproduce high quality amplified sound, because  it has low THD+N and  Also low harmonic distortion. Modern audio amplifier has filterless architecture, so it's no need any low pass filter and  the speakers directly connect to the amplifier output, which result in low cost and size. It has a protection circuit which automatically cuts off the power when occurring a fault as over-temperature or short-circuit. 
The module can be supplied by a power source with voltage from 2.5 V to 5.5 V DC, which make it suitable for Arduino sound projects, especially for MP3 and MP4 player projects. It is an ultra low cost but powerful and high-definition amplifier. The sound volume is quickly and easily adjusted with a built-in potentiometer, which capable to switch on and off and adjusting the output volume. It can apply in LCD Monitors, TV Projectors, Notebook Computers, Portable Speakers, Portable DVD Players, Game Machines, Cellular Phones, Speaker Phones, etc.
