Chip Description
The EG8303 is a 3W single-channel filterless Class D audio amplifier. High PSRR (power supply rejection ratio), differential input suppresses noise and RFI. 90% efficiency and minimal PCB area make the EG8303 ideal for handheld devices. A pop-free 1ms quick start time also makes the EG8303 ideal for PDA applications. The filterless architecture eliminates the output filter, reducing the number of external components, saving PCB space and system costs, and simplifying application design.
