NOTE:
6. Compliance to datasheet limits is assured by one or more methods: production test, characterization, and/or design.
7. A 550nm green LED is used in production test. The 550nm LED irradiance is calibrated to produce the same DATA count as a fluorescent light with
illuminance at the stated lux.
8. An 850nm IR LED is used in production test. The 850nm LED irradiance is calibrated to produce the same DATA_IR count as solar light with
illuminance at the stated lux.
9. C_b is the capacitance of the bus in pF.
