PAM8403QT Filterless 3W Class-D Stereo Audio Amplifier

The PAM8403 is a 3W, class-D audio amplifier. It offers low THD+N, allowing it to produce highquality sound reproduction. The new filterless architecture allows the device to drive the speaker directly, without needing low-pass output filters, which will save the system cost and PCB area. With the same numbers of external components, the efficiency of the PA.
