The CS35L00 is a 2.8 W high efficiency Hybrid Class-D audio amplifier with low idle current consumption and a selectable gain. The CS35L00 features an advanced closed-loop architecture to provide 0.02% THD+N at 1 W and -88 dB PSRR at 217 Hz. A flexible Hybrid Class-D output stage offers four modes of operation: Standard Class-D (SD) mode offers full audio bandwidth and high audio performance; Hybrid Class-D (HD) mode offers a substantial reduction in idle power consumption with an integrated ClassH controller; Reduced Frequency Class-D (FSD) mode reduces the output switching frequency, producing lower electromagnetic interference (EMI); and Reduced Frequency Hybrid Class-D (FHD) mode produces both the lower idle power consumption of HD mode and the reduced EMI benefits of FSD mode. Requiring minimal external components and PCB space, the CS35L00 is available in a 3.0 mm x 3.0 mm, 10-pin DFN package in Commercial grade (-10°C to +70°C).
