STK3410规格书
he 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 backlight/display brightness control but also infrared sensing to allow proximity estimation and gesture recognition 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 closeto human eye. The STK3410 is suitable 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 multiphotodiodes to distinguish the movement of the object. 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. The STK3410 operating voltage range is 1.7V to 3.6V.
