1. PIN DESCRIPTIONS FOR CS35L00

Pin Name

Pin Description

SD 1 Shutdown (Input) - Pulling this pin low places the CS35L00 in shutdown.

IN- 2 Negative Analog Input (Input) - Differential negative audio signal input

LFILT+ 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.

IN+ 4 Positive Analog Input (Input) - Differential positive audio signal input.

MODE 5 Switching Mode (Input) - Controls the output switching modes of the CS35L00.

OUT- 6 Negative PWM Output (Output) - Differential negative PWM output.

GAIN_SEL 7

Gain Select (Input) - Sets the gain of the amplifier. When pulled low, gain is +12 dB. When pulled high,

gain is +6 dB.

VBATT 8 Positive Analog Power Supply (Input) - Positive power supply input.

GND 9 Ground (Input) - Power supply ground.

OUT+ 10 Positive PWM Output (Output) - Differential Positive PWM output.

Thermal Pad -

Thermal Pad (Input) - Thermal relief pad for optimized heat dissipation. Connect to GND. See “DFN
