3.2W MONO CLASS D AUDIO AMPLIFIER

Description

The PAM8014 is a 3.2W mono filter-less class-D amplifier with high

PSRR and differential input that eliminate noise and RF rectification.

Features like greater than 90% efficiency and small PCB area make

the PAM8014 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 PAM8014 features short circuit protection and thermal shutdown.

The PAM8014 is available in U-WLB1313-9 package.
