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 18
Positive supply voltage.
DGND _ Digital Ground, pin 17
Analog Inputs
INR1+, INR2+ _ Channel 1 & 2 Rough Non-Inverting Inputs, pin 1, 12
Rough non-inverting analog inputs. The rough inputs settle non-linear currents to improve
linearity on the fine inputs and reduce harmonic distortion.
INR1-, INR2- _ Channel 1 & 2 Rough Inverting Inputs, pin 4, 9
Rough inverting analog inputs. The rough inputs settle non-linear currents to improve linearity
on the fine inputs and reduce harmonic distortion.
INF1+, INF2+ _ Channel 1 & 2 Fine Non-Inverting Input, pin 2, 11
Fine non-inverting analog inputs.
