NOTES:  3.  Full-scale frequency is the maximum operating frequency of the device without saturation.
4.  The temperature coefficient of output frequency is measured with constant irradiance as the temperature is varied between 25癈
and 70癈. The constant irradiance is sufficiently high that the output frequency is much greater than the dark frequency over the
entire temperature range.

NOTES:  5.  Nonlinearity is defined as the deviation of f
O
from a straight line between zero and full scale, expressed as a percent of full scale.
6.  Nonlinearity test condition: S0 = S1 = H, S2 = S3 = L.
7.  Principal frequency is the internal oscillator frequency, equivalent to divide-by-1 output selection.
