NOT RECOMMENDED FOR NEW DESIGN USE PAM8406 PAM8403 FILTERLESS 3W CLASS-D STEREO AUDIO AMPLIFIER Description Pin Assignments
The PAM8403 is a 3W, class-D audio amplifier. It offers low THD+N, allowing it to achieve high-quality sound reproduction. The new filterless architecture allows the device to drive the speaker directly, requiring no low-pass output filters, thus saving system cost and PCB area. With the same numbers of external components, the efficiency of the PAM8403 is much better than that of Class-AB cousins. It can extend the battery life, which makes it well-suited for portable applications. The PAM8403 is available in SOP-16 package.
Features
• 3W Output at 10% THD with a 4Ω Load and 5V Power Supply • Filterless, Low Quiescent Current and Low EMI • Low THD+N • Superior Low Noise •
Applications
Efficiency up to 90% • Short Circuit Protection • LCD Monitors / TV Projectors • Thermal Shutdown • Notebook Computers • Few External Components to Save the Space and Cost • Portable Speakers • Pb-Free Package • Portable DVD Players, Game Machines • Cellular Phones/Speaker Phones
Typical Applications Circuit
