01 / 01SD8818 is a high-efficiency, filterless 5.2W mono Class F audio amplifier. Its ultra-low EMI is ideal for portable devices with FM. Its single-ended input architecture and very high PSRR improve RF-noise rejection. Filterless PWM modulation and integrated gain reduce external components, PCB area, and system cost and simplify design. Up to 90% efficiency, fast startup, and a compact package make SD8818 suitable for portable audio products. Shutdown extends standby time; thermal protection improves reliability; POP-noise suppression simplifies system debugging.
