# _Description
A1 Positive Analog Input (Input) - Differential positive audio signal input.
A2 Switching Mode (Input) - Controls the output switching modes of the CS35L01/03.
A3 Negative PWM Output (Output) - Differential negative PWM output.
B1
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.
B2 Positive Analog Power Supply (Input) - Positive power supply input.
B3 Ground (Input) - Power supply ground.
C1 Negative Analog Input (Input) - Differential negative audio signal input.
C2 Shutdown (Input) - Pulling this net low places the CS35L01/03 in shutdown.
C3 Positive PWM Output (Output) - Differential Positive PWM output.
