STK3410

Description

The STK3410 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 backlght/display brightness control but also infrared sensing to allow proximity estimation and gesturerecognition featured with interrupt function.

For ambient light sensing, the STK3410 incorporates a photodiode, timing controller and ADC in a single chip. The excellent spectral response is designed to be close-to human eye. The STK3410 issuitable for detecting a wide range of light intensity environment. The maximum detecting light 
intensity is 1.7K Lux when using default setting.

For proximity sensing, the STK3410 also incorporates a photodiode, timing controller and ADC in 
the same chip. The spectral response of STK3410 is optimized for wavelength 940nm infrared light. The STK3410 provides programmable duty setting to drive IR LED and employs a noise cancellation scheme to highly reject unwanted ambient IR noise.

For gesture recognition,the STK3410 provides multi-photodiodes to distinguish the movement of theobject. It can be used to recognize one dimensions gesture recognition: left / right.

The STK3410 has excellent temperature compensation, robust on-chip refresh rate setting without 
external components. Software shutdown mode control is provided for power saving application. TheSTK3410 operating voltage range is 1.7V to 3.6V

Applications

Mobile Phone, Smart-phone, PDA
