DESCRIPTION
(1)
TOLERANT
(2)
NAME
NO.
SSTIMER
6
AI
Controls ramp time of OUT_X to minimize pop. Leave this pin floating
for BD mode. Requires capacitor of 2.2 nF to GND in AD mode. The
capacitor determines the ramp time.
STEST
26
DI
Factory test pin. Connect directly to DVSS.
VR_ANA
12
P
Internally regulated 1.8-V analog supply voltage. This pin must not be
used to power external devices.
VR_DIG
18
P
Internally regulated 1.8-V digital supply voltage. This pin must not be
used to power external devices.
VREG
31
P
Digital regulator output. Not to be used for powering external circuitry.

(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, SCLK, LRCLK, MCLK, SDIN, SDA, and SCL.
(3)
Maximum pin voltage should not exceed 6.0Vele
(4)
DC voltage + peak ac waveform measured at the pin should be below the allowed limit for all conditions.

This data was taken using 1 oz trace and copper pad that is soldered directly to a JEDEC standard high-k PCB. The thermal pad must
be soldered to a thermal land on the printed-circuit board. See TI Technical Briefs SLMA002 for more information about using the
HTQFP thermal pad
