The STK3311-A is an integrated ambient and infrared light to digital converter with a built-in IRLED 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 STK3311-A incorporates a photodiode, timing controller and ADC in a single chip. The excellent spectral response is designed to be close-to human eye. The STK3311-A 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 STK3311-A also incorporates a photodiode, timing controller and ADC i the same chip. The spectral response of STK3311-A is optimized for wavelength 940nm infrared light. The STK3311-A 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 STK3311-A has excellent temperature compensation, robust on-chip refresh rate setting withoutexternal components. Software shutdown mode control is provided for power saving application. The STK3311-A operating voltage range is 1.7V to 3.6V
