Bit 1 of gain control
1, 12,
GND
Ground connection for circuitry. Connected to the thermal pad
13, 24
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
The input for PC-Beep mode. PC-BEEP is enabled when a > 1.5-V (peak-to-peak) square wave is input to
PC-BEEP
14
I
PC-BEEP or PCB ENABLE is high.
If this terminal is high, the detection circuitry for PC-BEEP is overridden and passes PC-BEEP through the
PCB ENABLE
17
I
amplifier, regardless of its amplitude. If PCB ENABLE is floating or low, the amplifier continues to operate
normally.
PVDD
7, 18
I
Power supply for output stage
RHPIN
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
Input MUX control input. When this terminal is held high, the LHPIN or RHPIN and SE output is selected.
SE/BTL
15
I
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.
Thermal Pad
Connect to ground. Must be soldered down in all applications to properly secure the device on PC board.
