TSL2772

Light-to-Digital Converter with

Proximity Sensing

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 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.

Ordering Information and Content Guide appear at end of
