DESCRIPTION
NAME
NO.
Master/Slave select for determining direction of SYNC terminal. HIGH=Master mode, SYNC terminal is
MSTR/SLV
7
I
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
SYNC
8
I/O
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
VREG

O
driving other external circuitry.
AVCC
32
High-voltage analog power supply. Not internally connected to PVCCL.
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
Thermal Pad
—
internal or bottom layer for the best thermal performance. The Thermal Pad must be soldered to the
PCB for mechanical reliability.
