TCS3472

Color Light-to-Digital Converter with

IR Filter

The TCS3472 device provides a digital return of red, green, blue

(RGB), and clear light sensing values. An IR blocking filter,

integrated on-chip and localized to the color sensing

photodiodes, minimizes the IR spectral component of the

incoming light and allows color measurements to be made

accurately. The high sensitivity, wide dynamic range, and IR

blocking filter make the TCS3472 an ideal color sensor solution

for use under varying lighting conditions and through

attenuating materials.

The TCS3472 color sensor has a wide range of applications

including RGB LED backlight control, solid-state lighting,

health/fitness products, industrial process controls and medical

diagnostic equipment. In addition, the IR blocking filter enables

the TCS3472 to perform ambient light sensing (ALS). Ambient

light sensing is widely used in display-based products such as

cell phones, notebooks, and TVs to sense the lighting

environment and enable automatic display brightness for

optimal viewing and power savings. The TCS3472, itself, can

enter a lower-power wait state between light sensing

measurements to further reduce the average power

consumption.
