TCS3400 Color Light-to-Digital Converter The TCS3400 device provides color and IR (red, green, blue, clear General Description 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. Ordering Information and Content Guide appear at end of datasheet.
