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

Assumes default settings.

4. Applies to single 25.6 µs pulse measurement. By increasing irLED pulse width, 0.001 µW/cm2 under low light is

possible.

5. ALS Sensitivity under low light conditions can be improved by increasing ADC integration time. 10 mlx resolution

possible under the highest ADC integration time setting.
