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

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.
