ULTRA LOW EMI, 3W FILTERLESS

MONO CLASS-D AUDIO POWER AMPLIFIER

Description

The PAM8303D 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

PAM8303D 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 PAM8303D features short circuit protection and thermal

shutdown.

The PAM8303D is available in MSOP-8 and DFN3x3 8-pin packages.
