STK3310 Ambient Light Sensor and Proximity Sensor with Built-in IR LED Datasheet Version - 1.3 2014/05/02 STK3310 REV 1.3 1. Description OVERVIEW Built-in 850 nm LED Ambient Light Sensor Convert ambient light intensity to 16-bit digital data format 3rd generation ambient light sensor which closes to human-eye response and suppress IR portion – Read the Illuminance directly; unlike conventional solution calculated from two diodes’ data Flexible digital settings – Integration time : 0.2ms~6400ms Flexible interrupt setting – Interrupt while out-of-window – Persistence : 1 / 4 times Maximum detecting ambient light intensity : 6.5 K Lux General Fully digital control with I2C interface – 1.7 ~ 3.6V I2C interface Low power design – Standby mode – Wait mode Time-multiplexing for sensing VDD wide operation voltage : 1.7~3.6V Excellent temperature compensation: -40 to 85° C Package: 3.94x2.36x1.35(mm) Lead-free package (RoHS compliant) The STK3310 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 STK3310 incorporates a photodiode, timing controller and ADC in a single chip. The excellent spectral response is designed to be closeto human eye. The STK3310 is suitable for detecting a wide range of light int...
