PAM8014 Datasheet, PDF (1/9 Pages) Diodes Incorporated – 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.
