PAM8403 5V 2-Channel Stereo Audio Amplifier Module
This Audio Amplifier Module is based on PAM8403 which 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. It can extend the battery life, which makes it well-suited for portable applications.
- Advanced Micro Devices, volume: 1.85 * 2.11cm
- Excellent noise suppression in the case is not connected to the input audio, the ear close to the speaker can not hear any noise
- Two-channel stereo, 5V power supply can output 3W +3 W power, can directly drive 4 8 small speaker output power, full of energy, good sound quality.
- Unique without LC filter Class D digital power board, and can be used directly to the computer’s USB powered.
- Dual-panel wiring, properly solve the crosstalk between the ground potential balance and channel wiring
- Ultra-miniature design can easily be placed in the internal space for a variety of digital products, ultra-high zoom efficiency.
- All using the machine for the entire board soldering, hand soldering iron welding quality comparable!
