DIODES INCORPORATED
2x3W Stereo Differential Input Class D Audio Amplifier
with Up/Down Volume Control
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.
Pin Assignments
SO-16
PAM8407
The PAM8407 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 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.
