NOT RECOMMENDED FOR NEW DESIGN USE PAM8304 PAM8303D ULTRA LOW EMI, 3W FILTERLESS MONO CLASS-D AUDIO POWER AMPLIFIER Description Pin Assignments The PAM8303D is a 3W mono filterless Class-D amplifier with high U-DFN3030-8 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 externa 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 U-DFN3030-8 packages. Applications Features Cellular Phones/Smart Phones Ultra Low EMI, -20dB Better Than FCC Class-B 300MHz MP4/MP3 High Efficiency up to 90% 1W with an 8 Speaker GPS Shutdown Current <1A Digital Photo Frame Electronic 3W 10% THD Output with a 4 Load at 5V Supply Dictionary Portable Game Demanding Few External Components Superior Low Noise Machines without Input Supply Voltage from 2.8V to 5.5V Short Circuit Protection Thermal Shutdown Available in Space Saving Packages: MSOP-8, U- DFN3030-8 Totally Lead-Free & Fully RoHS Compliant (Note 1 & 2) Halogen and Antimony Free.
