NOTES:
7. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.
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 the section titled “ALS Range 1 Considerations” on page 10.
