The APDS-9900 series digital Ambient Light Sensing (ALS), IR LED and a complete Proximity Detection system. 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. The ALS provides a photopic response to light intensity in very low light condition or behind a dark faceplate. The APDS-9900 is particularly useful for display management with the purpose of extending battery life and providing optimum viewing in diverse lighting conditions.
