PAM8407数据手册Diodes中文资料规格书

描述 Description

The 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.

\t 

\tThe PAM8407 supports 2.5V to 6V operation make it idea for up to 4 cells alkaline battery applications.

\t 

\tFeatures 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.

\t 

\tThe PAM8407 built in auto recovery SCP (short circuit protection) and thermal shutdown.

\t 

\tThe PAM8407 is available in SO-16 package.
