Etek Microelectronics ETK8303
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
