10. The full scale ADC count value is slew-rate limited for short integration times and is limited by the 16-bit counter for long integration
3. Optical measurements are made using small-angle incident radiation from a light-emitting diode (LED) optical source.
4. The 470 nm input irradiance is supplied by an InGaN light-emitting diode with the following characteristics:
5. The 524 nm input irradiance is supplied by an InGaN light-emitting diode with the following characteristics:
6. The 640 nm input irradiance is supplied by a AlInGaP light-emitting diode with the following characteristics:
7. Illuminance responsivity R
8. Gain is controlled by the gain register (07h) described in the Register section.
9. Measurements taken when the Photodiode field value in the Photodiode Register (06h) is 00b and when the Prescaler field value
