Diodes Incorporated PAM8407 Audio Amplifier

Diodes PAM8407 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 make 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. The PAM8407 built-in auto-recovery SCP (short circuit protection) and thermal shutdown. The PAM8407 is available in the SO-16 package.
