General Description
The CS35L01 and the CS35L03 are 3.0W high efficien-
cy Hybrid Class-D audio amplifiers with low idle current
consumption.
The CS35L01/03 features an advanced closed-loop ar-
chitecture to provide 0.02% 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 of-
fers full audio bandwidth and high audio performance;
Hybrid Class-D (HD) mode offers a substantial reduc-
tion in idle power consumption with an integrated Class-
H controller; Reduced Frequency Class-D (FSD) mode
reduces the output switching frequency, producing low-
er 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 Commer-
cial grade (-10°C to +70°C). Please see “Ordering
Information” on page 33 for package options and gain
configurations.
