Terminal Functions
TERMINAL
NAME
I/O
DESCRIPTION
NO.
BYPASS
11
Tap to voltage divider for internal mid-supply bias generator
GAIN0
2
I
Bit 0 of gain control
GAIN1
3
I
Bit 1 of gain control
GND
1, 12,
13, 24
Ground connection for circuitry. Connected to the thermal pad.
LHPIN
6
I
Left channel headphone input, selected when SE/BTL is held high
LIN
10
I
Common left input for fully differential input. AC ground for single-ended inputs.
LLINEIN
5
I
Left channel line input, selected when SE/BTL is held low
LOUT+
4
O
Left channel positive output in BTL mode and positive output in SE mode
LOUT–
9
O
Left channel negative output in BTL mode and high-impedance in SE mode
PC-BEEP
14
I
The input for PC Beep mode. PC-BEEP is enabled when a > 1-V (peak-to-peak) square wave is input
to PC-BEEP or PCB ENABLE is high.
PCB ENABLE
17
I
If this terminal is high, the detection circuitry for PC-BEEP is overridden and passes PC-BEEP through
the amplifier, regardless of its amplitude. If PCB ENABLE is floating or low, the amplifier continues to
operate normally.
PVDD
RHPIN
7, 18
I
Power supply for output stage
20
I
Right channel headphone input, selected when SE/BTL is held high
RIN
8
I
Common right input for fully differential input. AC ground for single-ended inputs.
RLINEIN
23
I
Right channel line input, selected when SE/BTL is held low
ROUT+
21
O
Right channel positive output in BTL mode and positive output in SE mode
ROUT–
16
O
Right channel negative output in BTL mode and high-impedance in SE mode
SHUTDOWN
22
I
Places entire IC in shutdown mode when held low, except PC-BEEP remains active
SE/BTL
15
I
Input MUX control input. When this terminal is held high, the LHPIN or RHPIN and SE output is selected.
When this terminal is held low, the LLINEIN or RLINEIN and BTL output are selected.
VDD
19
I
Analog VDD input supply. This terminal needs to be isolated from PVDD to achieve highest performance.
