1. OVERVIEW
Description
The STK37660 is an integrated color(RGB) and infrared light to digital converter with I2C interface. This device provides not only color(RGB)/ambient
- Flag modes are included
- Persistence : 1/2/4/8/16 times
- Low noise design
- High ambient light suppression light sensing to allow robust backlight/display brightness control but also infrared sensing to allow proximity estimation featured with interrupt function.
- Color Sensor Convert ambient light intensity to 16-bit digital data format
For color(RGB)/ambient light sensing, the STK37660 incorporates Red, Green, Blue coating photodiode array and a reference Clear photodiode array, timing controller and ADC in a single chip to accurately measure the ambient light illumination and the environment CCT (correlated color temperature)
- RGB sensor which closes to ideal human-eye response and suppress IR portion to enhance the accuracy of color temperature calculation
- Flexible digital settings
- Long integration time : 8 steps IT
- 3.125 / 6.25 / 12.5 /... / 200 / 400 ms
- Short integration time : 20 steps IT
For proximity sensing, the STK37660 also incorporates
- 192 / 288 / ... / 2112 us a photodiode, timing controller and ADC in the same chip. The spectral response of STK37660 is optimized for wavelength 940nm infrared light. The STK37660 provides programmable current setting to drive IR LED and employs a noise cancellation scheme to highly reject unwanted ambient IR noise.
- Flexible interrupt setting
- Interrupt while out-of- window
- Persistence : 1/2/4/8 times
- Clear channel for different light source...
