PAM8403 Mini Two-channel 2X3W Class D Audio Power Amplification Module

This miniature PAM8403 3W Class D audio amplifier module offers low THD+N, allowing it to achieve high-quality sound reproduction, all in a form factor about the size of a US postage stamp! The new filterless architecture allows the Stereo Audio Amplifier to drive the speaker directly, requiring no low-pass output filters, thus saving system cost and PCB area. With the same number of external components, the efficiency of the Digital Subwoofer AmplifierPAM8403 is much better than that of its Class-AB cousins. 2 Channel Mini Audio Amplification Board can extend the battery life, which makes it well-suited for portable applications. D Class Power Amplifier can be used in any DIY design requiring a miniature audio amplifier, especially portable and mobile applications operating on battery power.
