Overview
The PAM8403 stereo power amplifier delivers Class AB performance with Class D efficiency. Its low-noise, filterless architecture eliminates the output low-pass filter required by conventional Class D amplifiers. Minimal external components reduce PCB space and system cost, making it ideal for portable applications. The PAM8403 delivers 3W output power at efficiency above 85%, with system shutdown and mute control functions. A proprietary circuit topology enhances noise immunity and reduces RFI.
