PAM8303D Document number: DSxxxxx Rev. 1 - 7 1 of 16 www.diodes.com November 2012 © Diodes Incorporated PAM8303D A Product Line of Diodes Incorporated ULTRA LOW EMI, 3W FILTERLESS MONO CLASS-D AUDIO POWER AMPLIFIER Description 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. Features • Ultra Low EMI, -20dB Better Than FCC Class-B @ 300MHz • High Efficiency up to 90% @1W with an 8Ω Speaker • Shutdown Current <1µA • 3W@10% THD Output with a 4Ω Load at 5V Supply • Demanding Few External Components • Superior Low Noise without Input • Supply Voltage from 2.8V to 5.5V • Short Circuit Protection • Thermal Shutdown • Available in Space Saving Packages: MSOP-8, DFN3x3-8 • Pb-Free Package Pin Assignments Applications • Cellular Phones/Smart Phones • MP4/MP3 • GPS • Digital Photo Frame • Electronic Dictionary • Portable Game Machines
