General Description
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 archi-
tecture 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 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 CS35L00 is available in a 3.0 mm x 3.0 mm,
10-pin DFN package in Commercial grade (-10°C to
+70°C). Please see “Ordering Information” on page 33
for package options and gain configurations.

# Pin Description
1 Shutdown (Input) - Pulling this pin low places the CS35L00 in shutdown.
2 Negative Analog Input (Input) - Differential negative audio signal input
3
Low Drop Out Regulator Filter (Output) - Bypass capacitor connection point for internal LDO. Con-
necting this net to VBATT places the device into SD mode.
4 Positive Analog Input (Input) - Differential positive audio signal input.
5 Switching Mode (Input) - Controls the output switching modes of the CS35L00.
6 Negative PWM Output (Output) - Differential negative PWM output.
7
Gain Select (Input) - Sets the gain of the amplifier. When pulled low, gain is +12 dB. When pulled high,
gain is +6 dB.
8 Positive Analog Power Supply (Input) - Positive power supply input.
9 Ground (Input) - Power supply ground.
10 Positive PWM Output (Output) - Differential Positive PWM output.
-
Thermal Pad (Input) - Thermal relief pad for optimized heat dissipation. Connect to GND. See “DFN
Thermal Pad” on page 31 for more information.
