5V DC Mini Class D Pam8403 USB Power Amplifier Board
5V DC Mini Class D Pam8403 USB Power Amplifier Board
The PAM8403 is a 3W, class-D audio amplifier. It offers low THD+N, 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. With the same numbers of external components, the efficiency of the PAM8403 is much better than that of Class-AB cousins.
The PAM8403 audio amplifier can extend the battery life, which makes it well-suited for portable applications. The board uses the typical circuit design of PAM8403, using MICRO USB power supply (reserved wire power interface), it is easy to use a universal mobile phone charger for its power supply, resistance devices are standardized patch technology, simple and stable.
Applications:
- LCD Monitors / TV Projectors
- Notebook Computers
- Portable Speakers
- Portable DVD Players, Game Machines
- Cellular Phones/Speaker Phones
Also check the PAM8610 Digital Amplifier Board available on Robocraze. It is a 15W per channel stereo Class-D audio amplifier with DC Volume Control. The working mode is Class D (PWM modulation type), and it features a switch function that, when shorted, will close the amplifier.
