DATASHEET ISL29147 Low Power Ambient Light and Proximity Sensor with Enhanced Infrared Rejection FN8409 Rev 3.00 January 6, 2015 The ISL29147 is a low power Ambient Light Sensor (ALS) and proximity (PROX) sensor.

It has a built-in IR-LED for the proximity function.

The ALS function measures the amount of light (in the visible spectrum) incident on the ISL29147.

The ALS function has a programmable ambient IR-rejection, which allows fine tuning of light source variations and is ideal for light

ISL29147 Features

* Internal IR-LED and sensor for a complete solution

* Ideal for applications under dark or tinted glass

* Enhanced ambient sunlight rejection to 40k Lux

* Programmable proximity sleep time between proximity measurements optimizes power consumption

* Hardware
