TERMINAL FUNCTIONS (continued)
TERMINAL
TYPE
5-V
TERMINATION
DESCRIPTION
(1)
TOLERANT
(2)
NAME
NO.
SCLK
23
DI
5-V
Serial audio data clock (shift clock). SCLK is the serial audio port
input data bit clock.
SDA
28
DIO
5-V
I2C serial control data interface input/output
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.
SSTIMER
6
AI
Controls ramp time of OUT_X for pop-free operation. Leave this pin
floating for BD mode. Requires capacitor of 2.2 nF to GND in AD
mode. The capacitor determines the ramp time of PWM outputs from
0% to 50%. For 2.2 nF, start/stop time is ~10 ms.
STEST
31
DI
Test pin. Connect directly to GND.
SUB_PWM–
39
DO
Subwoofer negative PWM output
SUB_PWM+
40
DO
Subwoofer positive PWM output
TEST1
7
DI
Test pin. Connect directly to GND.
TEST2
32
DI
Test pin. Connect directly to DVDD.
VALID
36
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.
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 1.8V digital supply voltage.This terminal must not
be used to power external devices.
VREG
43
P
3.3 Regulator output. Not to be used as s supply or connected to any
other components other than decoupling caps. Add decoupling
capacitors with pins 42 and 41.
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, SDA, SCL, and HPSEL.
(3)
DC voltage + peak ac waveform measured at the pin should be below the allowed limit for all conditions.
