A PRODUCT LINE OF
DIODES INCORPORATED
PAM8408
2x3W STEREO DIFFERENTIAL INPUT CLASS D
AUDIO AMPLIFIER WITH MEMORY UP/DOWN VOLUME
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.
Features
3W Output at 10% THD with a 4Load and 5V Supply
2.4W Output at 1% THD with a 4Load and 5V Supply
