STK33562
OVERVIEW
Description
The STK33562 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 STK33562 incorporates a photodiode, timing controller and ADC in a single chip. The excellent spectral response is designed to be close-to human eye. The STK33562 is suitable for detecting a wide range of light intensity environment.
For proximity sensing, the STK33562 also incorporates a photodiode, timing controller and ADC in the same chip. The spectral response of STK33562 is optimized for wavelength 940nm infrared light. The STK33562 provides programmable current setting to drive IR LED and employs a noise cancellation scheme to highly reject unwanted ambient IR noise.
The STK33562 has excellent temperature pensation,...
