PAM8304
3W MONO CLASS D AUDIO AMPLIFIER
Description
The PAM8304 is a mono filter-less Class-D amplifier with high SNR
and differential input that helps eliminate noise. The PAM8304
supports 2.8V to 6V operation make it idea for up to 4 cells alkaline
battery applications. The PAM8304 is capable of driving speaker
loads as low as 3Ω speaker with a 5V supply maximizing the output
power.
Features like greater than 90% efficiency and small PCB area make
the PAM8304 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 PAM8304 features short circuit protection, thermal shutdown and
under voltage lock-out.
The PAM8304 is available in DFN3030-8L and MOP-8L packages.
