3W/CH FILTERLESS STEREO CLASS-D AUDIO AMPLIFIER
Description
The PAM8404 is a 3W high efficiency filterless Class-D audio amplifier in 4mmX4mm and 2mmX2mm 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 handset 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 43µV noise floor.
PAM8404 is available in QFN 4mmx4mm and WCSP 2mmx2mm packages.
