Description

The PAM8408 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 gain will held when the chip is in shutdown mode.
 
The PAM8408 supports 2.5V to 6V operation make it idea for up to 4 cells alkaline battery applications.
 
Features like greater than 87% efficiency and small PCB area make the PAM8408 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 PAM8408 built in auto recovery SCP (short circuit protection) and thermal shutdown.
 
The PAM8408 is available in SO-16L package.
