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 Top View 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.
