OVERVIEW Description The STK3171-018 is an integrated ambient and infrared light to digital converter with the built-in IR LED and I2C Interface. This device provides not only ambient light sensing to allow robust backlight/display brightness control but also infrared sensing to allow proximity estimation featured with interrupt function. For ambient light sensing, the STK3171-018 incorporates a photodiode, amplifiers, and analog circuits in a single chip. The best spectral sensitivity is used to be...
