TOLERANT

NAME

NO.

(1)

RESET

16

DI

5-V

Pullup

Reset, active-low. A system reset is generated by applying a logic low

to this terminal. RESET is an asynchronous control signal that sets

the VALID outputs low, and places the PWM in the hard-mute state

(stops switching). Gain is immediately set to full attenuation. Upon the

release of RESET, if PDN is high, the system performs a 4- to 5-ms

device initialization and sets the gain, output configuration, and format

to the settings determined by the hardware pins.

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

SUB_PWM+

40

DO

Subwoofer positive PWM output

VALID

38

DO

Output indicating validity of all PWM channels, active high. Connect

this pin to an external power stage or leave floating.

VCLAMP_AB

60

P

Internally generated voltage supply for channels A and B gate drive.

Not to be used as a supply or connected to any component other than

the decoupling capacitor

VCLAMP_CD

54

P

Internally generated voltage supply for channels C and D gate drive.

Not to be used as a supply or connected to any component other than

the decoupling capacitor

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 digital supply voltage. This terminal must not

be used to power external devices.

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, and SDIN2.
