PAM8403 PAM-8403 8403 2.5V To 5V 2 Channel Mini Class D 3W+3W Stereo Audio Amplifiers 2.5-5V USB Power Dual Channels 3W Digital Power Audio Amplifier

The PAM8403 5V Two-channel Stereo is a 3W+3W, class-D audio amplifier. Allowing it to achieve high-quality sound reproduction. The new filter less 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.
