Introduction

AI Translation

The DIODES PAM8404 is a 3W high-efficiency filterless Class-D audio amplifier in 4mm × 4mm and 2mm × 2mm wafer chip scale (WCSP) packages that requires few external components. Features like 89% efficiency, -63dB PSRR, improved RF-rectification immunity, and very small PCB area make the PAM8404 Class-D amplifier ideal for cellular handsets and PDA applications. In cellular handsets, the earpiece, speaker phone, and melody ringer can each be driven by the PAM8404. The PAM8404 allows independent gain by summing signals from seperate sources, and has as low as 43μν noise floor. PAM8404 is available in QFN 4mm x 4mm and WCSP 2mm x 2mm packages.
