DESCRIPTION
AGND 26, 30
-
Analog ground for digital/analog cells in core
AV
CC
33
-
High-voltage analog power supply (8.5 V to 14 V)
AV
DD
29
O
5-V Regulated output capable of 100-mA output
AV
DD
REF 7
O
5-V Reference output—provided for connection to adjacent VREF terminal.
BSLN 13
I/O
Bootstrap I/O for left channel, negative high-side FET
BSLP 24
I/O
Bootstrap I/O for left channel, positive high-side FET
BSRN 48
I/O
Bootstrap I/O for right channel, negative high-side FET
BSRP 37
I/O
Bootstrap I/O for right channel, positive high-side FET
COSC 28
I/O
I/O for charge/discharging currents onto capacitor for ramp generator triangle wave biased at V2P5
LINN 6
I
Negative differential audio input for left channel
LINP 5
I
Positive differential audio input for left channel
LOUTN 16, 17
O
Class-D 1/2-H-bridge negative output for left channel
LOUTP 20, 21
O
Class-D 1/2-H-bridge positive output for left channel
MODE 34
I
Input for MODE control. A logic high on this pin places the amplifier in the variable output mode and the Class-D
outputs are disabled. A logic low on this pin places the amplifier in the Class-D mode and Class-D stereo outputs
are enabled. Variable outputs (VAROUTL and VAROUTR) are still enabled in Class-D mode to be used as
line-level outputs for external amplifiers.
MODE_OUT 35
O
Output for control of the variable output amplifiers. When the MODE pin (34) is a logic high, the MODE_OUT
pin is driven low. When the MODE pin (34) is a logic low, the MODE_OUT pin is driven high. This pin is
intended for MUTE control of an external headphone amplifier. Leave unconnected when not used for
headphone amplifier control.

C
.
PVCCR 46, 47
-
Power supply for right channel H-bridge (tied to pins 38 and 39 internally), not connected to PVCCL or AVC
C
.
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.
