11. PIN DESCRIPTION - CS5372

Power Supplies

Positive supply voltage.

Negative supply voltage.

Positive supply voltage.

Analog Inputs

Rough non-inverting analog inputs.

The rough inputs settle non-linear currents to improve

linearity on the fine inputs and reduce harmonic distortion.

Rough inverting analog inputs. The rough inputs settle non-linear currents to improve linearity
