View Associated Dev Toolsams TSL2772 Light to Digital Converter 
with Proximity Sensingams TSL2772 device family provides both ambient light sensing (ALS) and, when coupled with an external IRLED, proximity detection. The device family is based on the TAOS patented dual-diode technology that enables accurate ALS results and approximates human eye response to light intensity under a variety of lighting conditions. The TSL2772 ALS includes a reduced-gain mode that extends the operating range to 60klux in sunlight. The device package incorporates a UV-rejection filter that enables accurate ALS. The TSL2772 proximity detection includes improved signal-to-noise performance and selectable gain modes. A proximity offset register allows compensation for optical system crosstalk between the IR LED and the sensor. To prevent false proximity data measurement readings, a proximity saturation indicator bit signals that the internal analog circuitry has reached saturation.
