STK3310

深圳市政鸿微电子有限公司优势供应矽创原装传感器：STK3310
Description
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 close-to human eye. The STK3310 is suitable for detecting a wide range of light intensity environment. The maximum detecting light intensity is 6.5K Lux.

For proximity sensing, the STK3310 also incorporates a photodiode, timing controller and ADC in the same chip. The spectral response is optimized for wavelength 850nm infrared light. The STK3310 provides programmable duty setting to drive IR LED and employs a noise cancellation scheme to highly reject unwanted ambient IR noise.

The proximity sensor is optimized so that the black card at 0-cm can be detected. Please contact with sensortek for further application solution.

The STK3310 has excellent temperature compensation, robust on-chip refresh rate setting without external components. Software shutdown mode control is provided for power saving application. The STK3310 operating voltage range is 1.7V to 3.6V.
