Digital Ambient Light and Proximity Sensor 8-Pin SMD T/R

The APD device provides red, green, blue, and clear (RGBC) light sensing and proximity detection. The devices detect 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, such as 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.The color-sensing feature is useful in applications such as LED RGB backlight control, solid-state lighting, reflected LED color sampler, or fluorescent light color temperature detection. The integrated IR blocking filter makes this device an excellent ambient light sensor and color temperature monitor sensor.
