PAM8303DBSC

PAM8303DBSC is a 3W mono filterless Class-D amplifier with high PSRR and differential input that eliminates noise and RF rectification. Its features, like 90% efficiency and a small PCB area, make the PAM8303D 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, and simplifies application design. Applications include cellular phones/smart phones, MP4/MP3, GPS, digital photo frame electronic, dictionary portable game, machines.
