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.
