01 / 01SD8811 is a high-efficiency, filterless, mono 4.0W Class D audio power amplifier with anti-clipping. Its differential input architecture and very high PSRR improve RF-noise rejection. Anti-clipping resolves inconsistent output amplitudes from different audio sources while maintaining distortion-free audio. 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 SD8811 suitable for Bluetooth speakers and other portable audio products. Shutdown extends standby time; thermal protection improves reliability; POP-noise suppression simplifies system debugging. Available in DFN8 (2*2).
