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

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.

(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.
