LOUTP
20, 21
O
Class-D 1/2-H-bridge positive output for left channel
MUTE
34
I
A logic high on this pin disables the outputs. A low on this pin enables the outputs.
NC
31, 32,
35
Not internally connected

PVCCL
14, 15
Power supply for left channel H-bridge (tied to pins 22 and 23 internally), not connected to PVCCR or
AVCC.
PVCCL
22, 23
Power supply for left channel H-bridge (tied to pins 14 and 15 internally), not connected to PVCCR or
AVCC.
PVCCR

AVCC.
PVCCR
46, 47
Power supply for right channel H-bridge (tied to pins 38 and 39 internally), not connected to PVCCL or
AVCC.
REFGND
12
Ground for gain control circuitry. Connect to AGND. If using a DAC to control the volume, connect the DAC
ground to this terminal.
