Overview
PAM8403 Filterless 3W Class-D Stereo Audio Amplifier Key Features n 3W Output at 10% THD with a 4Ω Load and 5V Power Supply n Filterless, Low Quiescent Current and Low EMI n Low THD+N n Superior Low Noise n Efficiency up to 90% n Short Circuit Protection n Thermal Shutdown n Few External Components to Save the Space and Cost n Pb-Free Package Applications n LCD Monitors / TV Projectors n Notebook Computers n Portable Speakers n Portable DVD Players, Game Machines n Cellular Phones/Speaker Phones General Description 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 PAM8403 is much better than class-AB cousins.
It can extend the battery life, ideal for portable applications.
