APDS-9930

APDS-9930 is a digital proximity and ambient light sensor. It provides digital ambient light sensing (ALS), IR LED, and a complete proximity detection system in a single 8-pin package. The proximity function offers plug-and-play detection to 100mm (without front glass) thus eliminating the need for factory calibration of the end equipment or sub-assembly. 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 cell phone. 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. Applications include cell phone backlight dimming, cell phone touch-screen disable, notebook/monitor security, automatic speakerphone enable, automatic menu pop-up, and digital camera eye sensor.
