Pin Description
PIN
NAME
I/O
FUNCTION
1,12,13,24
GND/HS
Ground connection for circuitry, directly connected to thermal pad.
2
GAIN0
I
Bit 0 of gain control
3
GAIN1
I
Bit 1 of gain control
4
LOUT+
O
Left channel + output in BTL mode, + output in SE mode.
5
LLINEIN
I
Left channel line input, selected when HP/
LINE pin is held low.
6
LPHIN
I
Left channel headphone input, selected when HP/ LINE pin is held high.
7,18
PVDD
I
Power supply for output stages.
8
RIN
I
Common right input for fully differential inputs. AC ground for single-ended inputs.
9
LOUT-
O
Left channel - output in BTL mode, and high impedance in SE mode.
10
LIN
I
Common left input for fully differential inputs. AC ground for single-ended inputs.
11
BYPASS
Tap to voltage divider for internal mid-supply bias generator.
14
PC-BEEP
I
The input for PC-BEEP mode. PC-BEEP is enabled when at least eight continuous >
1-VPP (peak to peak) square waves is input to PC-BEEP pin.
15
SE/ BTL
I
Hold low for BTL mode, hold high for SE mode.
16
ROUT-
O
Right channel - output in BTL mode, high impedance state in SE mode.
17
HP/ LINE
I
MUX control input, hold high to select headphone inputs (6,20), hold low to select line
inputs (5,23).
19
VDD
Analog VDD input supply. This terminal needs to be isolated from PVDD to achieve
highest performance.
20
RHPIN
I
Right channel headphone input, selected when HP/ LINE pin is held high.
21
ROUT+
O
Right channel + output in BTL mode, positive output in SE mode.
22
SHUTDOWN
I
Places entire IC in shutdown mode when held low, expect PC-BEEP remains active.
23
RLINEIN
I
Right channel line input, selected when HP/ LINE pin is held low.
