Pin Functions
Pin
I/O
DESCRIPTION
NO.
NAME
AGND
26
-
Analog ground for digital/analog cells in core
AVCC
33
-
High-voltage analog power supply (8.5 V to 18 V)
AVDD
29
O
5-V Regulated output capable of 100-mA output
AVDDREF
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
FADE
30
I
Input for controlling volume ramp rate. A logic low on this pin places the amplifier in fade mode.
A logic high on this pin allows a quick transition to the desired volume setting when cycling SD
or during power-up.
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 -H-bridge negative output for left channel
LOUTP
20, 21
O
Class-D -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.
PGNDL
18, 19
-
Power ground for left channel H-bridge
PGNDR
42, 43
-
Power ground for right channel H-bridge
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
38,39
Power supply for right channel H-bridge (tied to pins 46 and 47 internally), not connected to
PVCCL or 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.
RINP
3
I
Positive differential audio input for right channel
RINN
2
I
Negative differential audio input for right channel
ROSC
27
I/O
Current setting resistor for ramp generator. Nominally equal to 1/8*VCC
ROUTN
44, 45
O
Class-D -H-bridge negative output for right channel
ROUTP
40, 41
O
Class-D -H-bridge positive output for right channel
SD
1
I
Shutdown signal for IC (low = shutdown, high = operational). TTL logic levels with compliance
to VCC.
VARDIFF
9
I
DC voltage to set the difference in gain between the Class-D and VAROUT outputs. Connect to
GND or AVDDREF if VAROUT outputs are unconnected.
VARMAX
10
I
DC voltage that sets the maximum gain for the VAROUT outputs. Connect to GND or AVDDREF
if VAROUT outputs are unconnected.
VAROUTL
31
O
Variable output for left channel audio. Line level output for driving external HP amplifier.
VAROUTR
32
O
Variable output for right channel audio. Line level output for driving external HP amplifier.
VCLAMPL
25
-
Internally generated voltage supply for left channel bootstrap capacitors.
VCLAMPR
36
-
Internally generated voltage supply for right channel bootstrap capacitors.
