• Description: Low Power Ambient Light And Proximity Sensor With Intelligent Interrupt And Sleep Modes
• Manufacturer: Intersil Corporation

Electrical Specifications
NOTES:
10. Ability to guarantee I
11. For ALS applications under light-distorting glass, please see the section titled ALS Range 1 Considerations.
12. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.

7. Nonlinearity is defined as: [(Measured Counts at 53 lux)-(Expected Counts at 53 lux)]/4095. Expected counts are calculated using an endpoint linear-
8. 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
9. An 850nm infrared LED is used to test PROX/IR sensitivity in an internal test mode.
