The CS35L01/03 features an advanced closed-loop architecture to provide THD+N at 1 W and -87 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 CS35L01 and CS35L03 are available in a mm x mm, 9-ball WLCSP package in Commercial grade -10°C to +70°C .
