STK3321 Ambient Light Sensor and Proximity Sensor with Built-in IR LED Preliminary Datasheet Version - 0.9 STK3321 REV 0.9 1. OVERVIEW Description The STK3321 is an integrated ambient and infrared light to digital converter with a 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 STK3321 incorporates a photodiode, timing controller and ADC in a single chip. The excellent spectral response is designed to be closeto human eye. The STK3321 is suitable for detecting a wide range of light intensity environment.
