PAM8403 is a miniature digital amplifier board. It is a 3W class-D stereo amplifier that provides low total harmonic distortion + noise (THD+N), enabling it to reproduce the finest-quality sound. Moreover, the latest architecture design does not require any low-pass filter at output hence it can drive the speaker directly, also saving the manufacturing cost and making it a more compact board.
The PAM8043 is much more efficient than the previous Class-AB amplifiers making it more reliable. The PAM8403 amplifier board can power two 3W + 3W stereo speakers and is driven by a simple 5V input. It is a great option for anyone looking for a Class-D stereo audio amplifier in a compact board design.
Features of PAM8403
- PCB size is about: length 30mm width 22mm overall height after installed is about 16mm
