描述 Description

The PAM8303C is a 3W mono filterless Class-D amplifier with high
PSRR and differential input that eliminate noise and RF rectification.
Features like 90% efficiency and small PCB area make the
PAM8303C Class-D amplifier ideal for cellular handsets. The filterless
architecture requires no external output filter, fewer external
components, less PCB area and lower system costs, and simplifies
application design.
The PAM8303C features short circuit protection and thermal
shutdown.
The PAM8303C is available in 9-ball WCSP, MSOP-8 and DFN 3x3
8-pin packages.
