PAM8303C

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. The filterless

architecture also simplifies application design. The PAM8303C

features

short-circuit

protection

and

thermal

shutdown.

The

PAM8303C is available in MSOP-8 and DFN 3030 8-pin packages.
