PAM8407DR

PAM8407DR is a filter-less class-D amplifier with high SNR and differential input that helps eliminate noise. Advanced 32-step up/down volume control minimizes external components and allows speaker volume control. The PAM8407 supports 2.5V to 6V operation, making it ideal for up to 4-cell alkaline battery applications. Features like greater than 87% efficiency and small PCB area make the PAM8407 Class-D amplifier ideal for portable applications. The output uses a filter-less architecture, minimizing the number of external components and PCB area whilst providing a high-performance, simple, and lower-cost system. Applications include PC speaker, wireless speaker, home sound systems, active speakers, and docking stations.
