PAM8403 Audio Amplifier Module
The PAM8403 is a 3W+3W, class-D stereo 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.
- Operating voltage: 2.5V-5.5V
- Maximum output power: 3W*2(5V 4Ω)
- Length: 29mm
- Width: 20mm
- Overall height after installed is about 16mm.
- Note:Please make sure the power supply is not more than 5.5V and please don’t do reverse polarity for “+” and “-“, or else, it will burn the board.
