Power Supplies
VA+ _ Positive Analog Power Supply, pin 8
Positive supply voltage.
VA- _ Negative Analog Power Supply, pin 7
Negative supply voltage.
VD _ Positive Digital Power Supply, pin 13, 18
Positive supply voltage.
DGND _ Digital Ground, pin 17
Analog Inputs
INR+ _ Rough Non-Inverting Input, pin 1
Rough non-inverting analog input. The rough input settles non-linear currents to improve
linearity on the fine input and reduce harmonic distortion.
INR- _ Rough Inverting Input, pin 4
Rough inverting analog input. The rough input settles non-linear currents to improve linearity
on the fine input and reduce harmonic distortion.
INF+ _ Fine Non-Inverting Input, pin 2
Fine non-inverting analog input.
