TSL2772 Datasheet | ams

Light-to-Digital Converter with Proximity Sensing General Description The TSL2772 device family provides both ambient light sensing (ALS) and, when coupled with an external IR LED, proximity detection. The device family is based on the ams OSRAM 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 60k lux 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 pensation 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.
