PAM8303C
ULTRA LOW EMI, 3W FILTERLESS
MONO CLASS-D AUDIO POWER AMPLIFIER
Description Pin Assignments
DFN3030 (B)
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.
