NOTES:
7. Cover glass assumes fixed infrared/visible light transmissivity ratio of 10.
8. The LED light source irradiance is calibrated to produce the same ALS count as a fluorescent light source of the same Lux level.
9. An 850nm infrared LED is used in production test for proximity/IR sensitivity testing.

10. All parameters in I C Electrical Specifications table are guaranteed by design and simulation.
11. C is the capacitance of the bus in pF.
