TCS3471
Color Light-to-Digital Converter
General Description
Figure 1:
Added Value Of Using TCS3471
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.
