CS35L03

CS35L01/03 2.9 W Mono Class-D Audio Amplifier with Low Idle Current CS35L01 & CS35L03 Features  Filterless Hybrid Class-D Architecture General Description The CS35L01 and the CS35L03 are 2.9W high efficiency Hybrid Class-D audio amplifiers with low idle current consumption. The CS35L01/03 features an advanced closed-loop architecture to provide 0.02% THD+N at 1 W and -75 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 1.2 mm x 1.2 mm, 9-ball WLCSP package in Commercial grade (-10°C to +70°C). Please see “Ordering Information” on page 33 for package options and gain configurations.     –
