ULTRA LOW EMI, 3W FILTERLESS

MONO CLASS-D AUDIO POWER AMPLIFIER

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.
