PAM 8403 Amplifier Module with Knob

PAM8403 is a basic 5V input amplifier board that can drive two 3W + 3W stereo speakers. It’s a great option for anyone looking for a Class-D stereo audio amplifier with a tiny footprint. The user can get high-quality audio reproduction from a stereo input using this amplifier. It also has a unique function in that it can drive speakers directly from the output. . It offers low THD+N, 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. 

This PAM8403 Amplifier module differs from the conventional PAM8403 Amplifier board in this module it allows us to have more control over the output provided by the IC. By control, we mean that this amplifier module board comes with a knob that allows you to adjust the output. The PAM8403 IC provides high-definition sound quality and highlights the benefits of digital chips. The circuit uses the most reasonable peripheral arrangement, and the power supply filter is increased to 470uf.
