The PAM8303D is a 3W mono filterless Class-D amplifier with high PSRR and differential input that eliminate noise and RF rectification. Features like 90% efficiency and 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. The PAM8303D features short circuit protection and thermal shutdown. The PAM8303D is available in MSOP-8 and DFN3x3 8-pin packages.
