Full-scale frequency is the maximum operating frequency of the device without saturation.
Nonlinearity is defined as the deviation of fO from a straight line between zero and full scale, expressed as a percent of full scale.
§Principal frequency is the internal oscillator frequency, equivalent to divide-by-1 output selection.
