DESCRIPTION
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.
Factory test pin. Connect directly to DVSS.
Internally regulated 1.8-V analog supply voltage. This pin must not be
used to power external devices.
Internally regulated 1.8-V digital supply voltage. This pin must not be
used to power external devices.
Digital regulator output. Not to be used for powering external circuitry.

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.
5-V tolerant inputs are PDN, RESET, SCLK, LRCLK, MCLK, SDIN, SDA, and SCL.
Maximum pin voltage should not exceed 6.0Vele
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
