DATASHEET ISL29038 Low Power Ambient Light and Proximity Sensor with Enhanced Infrared Rejection FN7851 Rev 1.00 January 23, 2015 The ISL29038 is a low power Ambient Light Sensor (ALS) and proximity (PROX) sensor.

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

The ALS function measures the amount of light (in the visible spectrum) incident on the ISL29038.

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

ISL29038 Features

* 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 interrupt - no polling required

* Programmable IR com
