NAME NO.
SCLK 23 DI 5-V Serial audio data clock (shift clock). SCLK is the serial audio port
input data bit clock.
SDIN1 25 DI 5-V Serial audio data 1 input is one of the serial data input ports. SDIN1
supports three discrete (stereo) data formats.
SDIN2 24 DI 5-V Serial audio data 2 input is one of the serial data input ports. SDIN2
supports three discrete (stereo) data formats.
SUB_PWM– 39 DO Subwoofer negative PWM output. BD modulated signal.
SUB_PWM+ 40 DO Subwoofer positive PWM output. BD modulated signal.
TEST1 7 DI Test pin. Connect directly to GND.
VALID 38 DO Output indicating validity of ALL PWM channels, active-high. This pin
is connected to an external power stage. If no external power stage is
used, leave this pin floating.
VDD 6 P Power supply for VREG (10.8 V to 13.2 V)
VR_ANA 14 P Internally regulated 1.8-V analog supply voltage. This terminal must
not be used to power external devices.
VR_DIG 27 P Internally regulated 1.8-V analog supply voltage. This terminal must
not be used to power external devices.
VREG 43 P Digital regulator output. Not to be used for powering external circuitry.
VREG_EN 18 DI Pulldown Voltage regulator enable. Connect directly to GND.

(1) Stresses beyond those listed under absolute ratings may cause permanent damage to the device. These are stress ratings only and
functional operation of the device at these or any other conditions beyond those indicated under recommended operation conditions are
not implied. Exposure to absolute-maximum conditions for extended periods may affect device reliability.
(2) 5-V tolerant inputs are PDN, RESET, MUTE, SCLK, LRCLK, MCLK, SDIN1, SDIN2.
