TCS3490
Color Light-to-Digital Converter
General Description
The TCS3490 device provides color and IR (red, green, blue, clear and IR) light sensing. The color sensing provides for improved accuracy lux and color temperature measurements typically used to adjust the backlight intensity and correct the display color gamut. Additionally it can be used for light source type detection as it reports the IR content of the light.
For further understanding in regards to the contents of the datasheet, please refer to the Reference Guide located at the end of the document.
