Ambient light and proximity sensor
21 March 2012, Opto-Electronics
The APDS-9900 from Avago integrates a digital ambient light and proximity sensor (ALS), IR LED and a complete proximity detection system in a single 8-pin package. The proximity function offers plug-and-play detection to 100 mm (without front glass) thus eliminating the need for factory calibration of the end equipment or subassembly. The proximity detection feature operates well from bright sunlight to dark rooms.
The wide dynamic range also allows for operation in short distance detection behind dark glass such as a cellphone. In addition, an internal state machine provides the ability to put the device into a low power mode in between ALS and proximity measurements, providing very low average power consumption. The ALS provides a photopic response to light intensity in very low light conditions or behind a dark faceplate.
The proximity function is targeted specifically towards near field proximity applications. The addition of the micro-optics lenses within the module provide highly efficient transmission and reception of infrared energy which lowers overall power dissipation.
