Overview
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 light sensor applications under dark protective glass.
The ALS provides a 12-bit measurement.
A passive optical filter removes unwanted wavelengths (IR or Ultraviolet) to ensure accurate ALS measurement.
The proximity function includes a new offset adjustment to compensate for the IR light reflected off the inside of the protective glass cover and back to the ISL29038 sensor.
This offset adjustment allows the sensor to compensate for these internal reflections and preserve the dynamic range of the...
