3W Output at 10% THD with a 4 Ω Load and 5V Power Supply Filterless, Low Quiescent Current and Low EMI Low THD+N 64-step Digital Volume Control Superior Low Noise Low pop noise Efficiency up to 90% Short Circuit Protection Thermal Shutdown Few External Components to Save Space and Cost
The PAM8803 is a 3W, class-D audio amplifier with 64-step digital volume control. It offers low THD+N, allowing it to produce high-quality sound reproduction. The new filterless architecture allows the device to drive the speaker directly, without needing low-pass output filters , which will save 30% system cost and 75% PCB area.
With the same numbers of external components, the efficiency of the PAM8803 is much better than class-AB cousins. It can extend the battery life, ideal for portable applications.
