Class-D 1/2-H-bridge positive output for right channel.
Power supply for right channel H-bridge, not connected to PVCCL or AVCC.
Bootstrap I/O for right channel, positive high-side FET.
Analog ground for digital/analog cells in core.
I/O for current setting resistor of ramp generator.
Master/Slave select for determining direction of SYNC terminal.
HIGH=Master mode, SYNC terminal is an output; LOW = slave mode,
SYNC terminal accepts a clock input. TTL logic levels with compliance to
VREG.
Clock input/output for synchronizing multiple class-D devices. Direction
determined by MSTR/SLV terminal. Input signal not to exceed VREG.
Reference for preamplifier. Nominally equal to 1.25 V. Also controls start-up
time via external capacitor sizing.
4-V regulated output for use by internal cells, GAINx, MUTE, and
MSTR/SLV pins only. Not specified for driving other external circuitry.
High-voltage analog power supply. Not internally connected to PVCCR or
PVCCL.

NC
Not internally connected.
Connect to AGND and PGND – should be star point for both grounds.
Internal resistive connection to AGND and PGND. Thermal vias on the PCB
should connect this pad to a large copper area on an internal or bottom
layer for the best thermal performance.
The Thermal Pad must be soldered
to the PCB for mechanical reliability.
