Notes:

1. Unless specifically stated in "Conditions", electrical data assumes ambient light levels < 1 klx.

2. Proximity-detection performance may be degraded, especially when there is high optical crosstalk, if the LED supply

and voltage drop allow the driver to saturate and current regulation is lost.

3. Guaranteed by design and characterization.

4. Represents the time during which the device is drawing a current equal to Iactive for power estimation purposes.

Assumes default settings.
