PAM8003 Filterless 2W Class-D Stereo Audio Amplifier Key Features General Description n 2W Output at 10% THD with a 4 Ω Load and 5V Power Supply n Filterless, Low Quiescent Current and Low EMI n Low THD+N n 64-step DC Volume Control n Superior Low Noise n Short Circuit Protection n Thermal Shutdown n Few External Components to Save the Space and Cost n Pb-Free Package Applications n n n n n The PAM8003 is a 2W, class-D audio amplifier. It offers low THD+N, allowing it to achieve highquality sound reproduction. The new filterless 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 PAM8003is much better than that of class-AB cousins. It can extend the battery life, ideal for portable applications. The PAM8003is available in SOP-16L, MSOP-10L and TQFN3*3-16L package.
