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.
