Power Supply Connections
VA+ - Positive Analog Power, PIN 3.
Positive analog supply. Nominally +5 volts.
VA- - Negative Analog Power, PIN 5.
Negative analog supply. Nominally -5 volts.
AGND1, AGND2, AGND3 - Analog Grounds, PINS 1, 4, 25.
Analog ground reference.
VD+ - Positive Digital Power, PIN 16.
Positive supply for the digital section. Nominally +5 volts.
DGND - Digital Ground, PIN 17.
Digital ground for the digital section.
Analog Outputs
VREF- - Voltage Reference Output, PIN 28.
Nominally -3.68 volts. Normally connected to a 0.1µF ceramic capacitor in parallel with a
10µF or larger electrolytic capacitor. Note the negative output polarity.
AOUTL - Analog Left Channel Output, PIN 2.
Analog output for the left channel. Typically 4V peak-to-peak for a full-scale input signal.
AOUTR - Analog Right Channel Output, PIN 26.
Analog output for the right channel. Typically 4V peak-to-peak for a full-scale input signal.
