型號: STK3310
產(chǎn)品詳情

Description

The STK3310 is an integrated ambient and infrared lightto digital converter with a built-in IR LED and I2Cinterface. This device provides not only ambient lightsensing to allow robust backlight/display brightnesscontrol but also infrared sensing to allow proximityestimation featured with interrupt function.For ambient light sensing, the STK3310 incorporates aphotodiode, 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 awide range of light intensity environment. The maximumdetecting light intensity is 6.5K Lux.

For proximity sensing, the STK3310 also incorporates aphotodiode, timing controller and ADC in the same chip.The spectral response is optimized for wavelength850nm infrared light. The STK3310 providesprogrammable duty setting to drive IR LED and employsa noise cancellation scheme to highly reject unwantedambient IR noise.

The proximity sensor is optimized so that the black cardat 0-cm can be detected. Please contact with sensortekfor further application solution.The STK3310 has excellent temperature compensation,robust on-chip refresh rate setting without externalcomponents. Software shutdown mode control isprovided for power saving application. The STK3310operating voltage range is 1.7V to 3.6V
