PAM8403 บอร์ดขยายเสียง 2 แชนแนล คลาส D ขนาน 3watt x 2 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 Efficiency up to 90% Short Circuit Protection Thermal Shutdown Few External Components to Save the Space and Cost Pb-Free Package
