1. Revision Information Date Revision Description Comment
2008/03/24 V1.0 Initial Release 2012/07/31 V1.1 Update PCB
2. PAM8403H General Description
The PAM8403H is a 3W, class-D audio amplifier. It offers low THD+N, allowing it to achieve high-quality sound reproduction. The new filter less architecture allows the device to drive the speaker directly, requiring no low- pass output filters, thus to save the 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, ideal for portable applications.
3. Key Features
3W Output at 10% THD with a 4Ω Load and 5V Thermal Shutdown Power Supply Few External Components to Save the Space Filter less, Low Quiescent Current and Low EMI and Cost Low THD+N Pb-Free Package Superior Low Noise Efficiency up to 90% Short Circuit Protection This application note contains new product information. Diodes, Inc. reserves the right to modify the product specification without notice. No liability isassumed as a result of the use of this product. No rights under any patent accompany the sale of the product.
