Chip Description
The EG8305 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 EG8305 ideal for handheld device applications. A pop-free 1ms quick start time also makes the EG8305 an ideal choice for PDA applications. The filterless architecture eliminates the output filter, reducing the number of external components, saving PCB area and system cost, and simplifying application design.
