TCS3400 Color Sensor

Color light-to-digital converter with 5th IR Channel Vdd I²C


The TCS3400 device family provides color and IR (red, green, blue, clear and IR) ambient light sensing. The improved accuracy lux and color temperature measurement from color sensing is 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.
