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 IIRDR 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.

Electrical Specifications VDD = 3.0V, TA = +25°C, REXT = 499kΩ 1% tolerance. Boldface limits apply over the operating

temperature range, -40°C to +85°C.
