PAM8303CBYC

PAM8303CBYC is a 3W mono, filterless Class-D amplifier with high PSRR and differential input that eliminates 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. Typical applications include cellular phones/smart phones, MP4/MP3, GPS, digital photo frame, electronic dictionary, portable game machines.
