TERMINAL FUNCTIONS (continued)

TERMINAL

TYPE

5-V

TERMINATION

DESCRIPTION

(1)

TOLERANT

(2)

NAME

NO.

RESET

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

restores the DAP to its default conditions, sets the VALID outputs low,

and places the PWM in the hard-mute state (stops switching). Master

volume 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 volume at mute.

SCL

5-V

I2C serial control clock input

SCLK

5-V

Serial audio data clock (shift clock). SCLK is the serial audio port input

data bit clock.

SDA

DIO

5-V

I2C serial control data interface input/output

SDIN1

5-V

Serial audio data-1 input is one of the serial data input ports. SDIN1

supports three discrete (stereo) data formats.

SDIN2

5-V

Serial audio data-2 input is one of the serial data input ports. SDIN2

supports three discrete (stereo) data formats.

STEST

Test terminal. Connect directly to GND.

SUB_PWM–

Subwoofer negative PWM output

SUB_PWM+

Subwoofer positive PWM output

TEST2

Test terminal. Connect directly to DVDD.

VALID

Output indicating validity of ALL PWM channels, active-high. This

terminal is connected to an external power stage. If no external power

stage is used, leave this terminal floating.

VCLAMP_AB

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

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

Internally regulated 1.8-V analog supply voltage. This terminal must

not be used to power external devices.

VR_DIG

Internally regulated 1.8-V digital supply voltage. This terminal must not

be used to power external devices.

VREG_EN

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, SDA, SCL, and HPSEL.
