DESCRIPTION
NAME
NO.
I/O
DESCRIPTION
ADDRESS0
4
I
Bit 0 of user-setable portion of device’s I2C address.
ADDRESS1
10
I
Bit 1 of user-setable portion of device’s I2C address.
BYPASS
21
Tap to voltage divider for internal midsupply bias generator.
GND
1, 13
Ground connection for circuitry. Connect to thermal pad
LHPIN
7
I
Left-channel headphone input, selected when SE/BTL is held high, or programmed via I2C.
LIN
5
I
Common left input for fully differential input. AC ground for single-ended inputs.
LLINEIN
6
I
Left-channel line input, selected when SE/BTL is held low, or programmed via I2C.
LOUT+
2
O
Left-channel positive output in BTL mode, and positive output in SE mode.
LOUT
24
O
Left-channel negative output in BTL mode, and high impedance in SE mode.
PC-BEEP
3
I
The input for PC-BEEP mode which is enabled when a > 1-V (peak-to-peak) square wave is input to this
terminal, when PCB ENABLE is held high, or programmed via I2C. If not used, ground this terminal.
I2CVDD
16
I
The voltage on this terminal sets the trip points for the I2C interface. If the system I2C bus is running at 3.3 V,
then tie this terminal to 3.3 V. If the system I2C bus is running at 5 V, then tie this terminal to 5 V.
PVDD
8, 19
I
Power supply
RHPIN
17
I
Right-channel headphone input, selected when SE/BTL is held high, or programmed via I2C.
RIN
9
I
Common right input for fully differential input. AC ground for single-ended inputs.
RLINEIN
18
I
Right-channel line input, selected when SE/BTL is held low, or programmed via I2C.
ROUT+
12
O
Right-channel positive output in BTL mode, and positive output in SE mode.
ROUT
14
O
Right-channel negative output in BTL mode, and high impedance in SE mode.
SCL
23
I
I2C clock line
SDA
15
Serial data line of the I2C bus. Pullup resistor must comply with the I2C standard: minimum value = 3 k
,
maximum value = 19 k
. Pull up to I2CVDD
SE/BTL
11
I
Input MUX control input. When this terminal is held high, the LHPIN or RHPIN, and the SE output are
selected. When this terminal is held low, the LLINEIN or RLINEIN, and the BTL output are selected. This
functionality can also be programmed via I2C.
SHUTDOWN
22
I
When held low, this terminal places the device in the shutdown mode, except for the PC-BEEP input and the
I2C bus.
