NAME
FUNCTION
1
BIAS
Analog Bias Voltage. Bypass BIAS to GND with a 10FF capacitor.
2
VL
Logic Supply Voltage. Connect VL to a 2.7V to 5V logic supply. Bypass VL to GND with a 0.1FF
capacitor.
3, 4, 10, 11
I.C.
Internally Connected. Leave unconnected.
5
INLP
Left Audio Positive Input. Either input of each pair can be used as a single-ended input, with the
complementary input bypassed to GND.
6
INLM
Left Audio Negative Input. Either input of each pair can be used as a single-ended input, with the
complementary input bypassed to GND.
7
VDD
Power-Supply Input. Connect VDD to the supply voltage. Bypass VDD to GND through a 1FF
capacitor.
8
INRM
Right Audio Negative Input. Either input of each pair can be used as a single-ended input, with the
complementary input bypassed to GND.
9
INRP
Right Audio Positive Input. Either input of each pair can be used as a single-ended input, with the
complementary input bypassed to GND.
12
SHDN
Shutdown Input. Drive SHDN low to power down the device.
13
MUTE
Mute Input. Drive MUTE low to mute the outputs. The outputs are low impedance in mute.
