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