NOTES:
6. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.
7. An LED is used in production test. The LED irradiance is calibrated to produce the same DATA count against a fluorescent light source of the same lux
level.
8. An 850nm infrared LED is used to test PROX/IR sensitivity in an internal test mode.
9. Ability to guarantee I IRDR leakage of ~1nA is limited by test hardware.
10. For ALS applications under light-distorting glass, please see “ALS Range 1 Considerations” on page 10.
I 2 C Electrical Specifications For SCL and SDA unless otherwise noted, V DD = 3V, T A = +25°C, R EXT = 499k ? 1% tolerance
(Note 11 ). Boldface limits apply over the operating temperature range, -40°C to +85°C.
