The PAM8403 5V Two Channel Stereo Audio Amplifier Module is a compact Class-D two-channel amplifier board built around the PAM8403 IC, delivering separate left and right channel audio output from a 2.5V to 5.5V supply — making it the only stereo amplifier module and the simplest to power, since the recommended 5V supply means it runs directly from a USB power bank, a computer USB port, or any standard 5V phone charger without needing a separate DC adapter. This pam8403 module accepts a stereo analog audio input from any phone, tablet, or audio source with a standard headphone jack and amplifies both channels independently to drive two separate speakers for true left and right stereo sound.
The pam8403 amplifier board’s Class-D design runs at 87% efficiency, so the board stays cool during normal operation even though it handles more total power than the LM386 module — at 3W per channel across two channels, the PAM8403 delivers more usable audio power for stereo speaker setups while remaining safe to touch without a heat sink under typical listening volumes. The amplifier board 5v’s 80dB signal-to-noise ratio keeps background hiss low enough that music and voice content sounds clean through small bookshelf or satellite speakers.
The pam amplifier board 24dB maximum gain and -58dB power supply rejection ratio ensure the output stays free of interference even when powered from a shared USB supply rail along side other electronics components. Available from StemVolt, delivering genuine electronics components with trusted quality.
