VA+ - Positive Analog Power, Pin 12.
Positive analog supply. Nominally +5 volts.
VA- - Negative Analog Power, Pin 13.
Negative analog supply. Nominally -5 volts.
AGNDL - Left Channel Analog Ground, Pin 15.
Analog ground reference for the left channel.
AGNDR - Right Channel Analog Ground, Pin 10.
Analog ground reference for the right channel.
VD+ - Positive Digital Power, Pin 4.
Positive supply for the digital section. Nominally +5 volts. Applying power to VD+ prior to
VA+ creates a SCR latch-up condition. Refer to Figure 2 for the recommended power
connections.
DGND - Digital Ground, Pin 5.
Digital ground for the digital section.
