APDS-9950

Avago's APDS-9950 Digital Proximity RGB & Ambient Light Sensor provides red, green, blue, and clear (RGBC) light sensing and proximity detection. It detects light intensity under a variety of lighting conditions and through a variety of attenuation materials, including dark glass. The proximity detection feature allows a large dynamic range of operation for accurate distance detection, like in a cell phone, for detecting when the user positions the phone close to their ear. IR LED sink current is factory-trimmed to provide consistent proximity response without requiring customer calibrations. An internal state machine provides the ability to put the device into a low power state in between proximity and RGBC measurements, providing very low average power consumption.
