The PAM8403 is a two-channel stereo mini class-D audio amplifier. It is a small, low-power IC that is designed to amplify audio signals in portable and battery-powered devices. The amplifier has a compact size, low noise, and low distortion, making it suitable for a wide range of applications.

The PAM8403 operates on a voltage supply of 2.5V-5.5V and can deliver a maximum output power of 3W per channel into a 4-ohm load with a 5V power supply. It also has a high efficiency of up to 90% which makes it ideal for use in battery-powered applications.

The PAM8403 includes several protection features such as short circuit protection and thermal shutdown. It also includes a built-in power-on reset function, which ensures that the amplifier starts up correctly and safely.

The PAM8403 is widely used in portable speakers, MP3 players, portable DVD players, and other small audio systems. It is also commonly used in DIY projects, such as portable speakers and other audio projects.

The PAM8403 has a simple pinout and can be easily interfaced with microcontrollers or other audio sources using a few external components. The amplifier also has a built-in gain control which can be set to the required level using a single external resistor.
