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.
HP/LINE
17
I
HP/LINE is the input MUX control input. When the HP/LINE terminal is held high, the headphone inputs
(LHPIN or RHPIN [6, 20]) are active. When the HP/LINE terminal is held low, the line BTL inputs (LLINEIN
or RLINEIN [5, 23]) are active.
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
Hold SE/BTL low for BTL mode and hold high for SE mode.
VDD
19
I
Analog VDD input supply. This terminal needs to be isolated from PVDD to achieve highest performance.
