No Preview Available ! General Description The ET8303 is a 3W mono filterless classD amplifier with high PSRR and differential input that eliminate noise and RF rectification. Features like 90% efficiency and small PCB area make the ET8303 classD 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 ET8303 features short circuit protection and thermal shutdown. The ET8303 is available in DFN 3x3 8pin or MSOP8 packages. Features Ultra Low EMI, 20dB Better Than FCC ClassB @ 300MHz High Efficiency up to 90% @1W with an 8Ω Speaker Shutdown Current <1μA 3W@10% THD Output with a 4ΩLoad at 5V Supply Demanding Few External Components Superior Low Noise without Input Supply Voltage from 2.8V to 5.5 V Short Circuit Protection Thermal Shutdown Available in Space Saving Packages: DFN8(ET8303Y)、MSOP8(ET8303) PbFree Package DFN8 print mark: Application Cellular Phones/Smart Phones MP4/MP3 GPS Digital Photo Frame Electronic Dictionary Portable Game Machines Pin Configuration 1 page
