Digital Power Amplifier For Sound

The PAM8403 5V Two-channel Stereo is a 3W+3W, class-D audio amplifier, allowing it to achieve high-quality sound reproduction. The new filterless architecture allows the device to drive the speaker directly, requiring no low-pass output filters, thus saving system cost and PCB area. You can power the pam8403 amplifier board 5v using your mobile charger or can be by a computer USB plug. You can use two speakers 3/5 watts on both sides L and R. And connect the Audio cord to the LTR portion. With the same number of external components, the efficiency of the PAM 8403 is much better than that of its Class-AB cousins. It can extend the battery life, which makes it well-suited for portable applications. 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 power supply never exceeds 5.5V else IC will get damaged. Use a regulated power supply. Applications: LCD Monitors / TV Projectors Notebook Computers Portable Speakers Portable DVD Players, Game Machines Cellular Phones/Speaker Phones Also check the 5V DC Mini Class D Pam8403 USB Power Amplifier Board available on Robocraze. It is a 3W, class-D audio amplifier with low Total Harmonic Distortion plus Noise (THD+N), enabling high-quality sound reproduction. The filterless architecture allows it to drive the speaker directly, eliminating the need for low-pass output filters and reducing system cost and PCB area. The amplifier operates on a 5V power supply and is designed for Bluetooth audio receiver module dedicated interfaces.
