TCS3471

Color Light-to-Digital Converter

The TCS3471 family of devices provides red, green, blue, and

clear light sensing (RGBC) that detects light intensity under a

variety of lighting conditions and through a variety of

attenuation materials. An internal state machine provides the

ability to put the device into a low power mode in between

RGBC measurements providing very low average power

consumption.

The TCS3471 is directly useful in lighting conditions containing

minimal IR content such as LED RGB backlight control, reflected

LED color sampler, or fluorescent light color temperature

detector. With the addition of an IR blocking filter, the device is

an excellent ambient light sensor, color temperature monitor,

and general purpose color sensor.

Ordering Information and Content Guide appear at end of

datasheet.
