TCS3472
Color Light-to-Digital Converter with
IR Filter
General Description
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.
