NEGATIVE ANALOG POWER
CRYSTAL OR CLOCK INPUT
Positive analog supply. Nominally +5 volts.
Negative analog supply. Nominally -5 volts.
Analog ground reference.
Positive supply for the digital section. Nominally +5 volts.
Digital ground for the digital section.
Nominally -3.68 volts. Normally connected to a 0.1 F ceramic capacitor in parallel with a
10 F or larger electrolytic capacitor. Note the negative output polarity.
Analog output for the left channel. Typically 4V peak-to-peak for a full-scale input signal.
Analog output for the right channel. Typically 4V peak-to-peak for a full-scale input signal.
