Rough non-inverting analog inputs. The rough inputs settle non-linear currents to improve
linearity on the fine inputs and reduce harmonic distortion.
Fine non-inverting analog inputs.
Fine inverting analog inputs.
Rough inverting analog inputs. The rough inputs settle non-linear currents to improve linearity
on the fine inputs and reduce harmonic distortion.
