Datasheet - Apr. 2013 - V1.0
General Description
Figure TCS3472 – 1:
Key Benefits and Features
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.
Benefits
Features
Enables accurate color and light sensing
measurements under varying lighting
conditions by minimizing IR and UV spectral
component effects.
Red, Green, Blue (RGB), and Clear Light
Sensing with IR Blocking Filter
• Programmable Analog Gain and Integration Time
• 3,800,000:1 Dynamic Range
• Very High Sensitivity — Ideally Suited for Operation
Behind Dark Glass
Programmable interrupt pin enables level-style
interrupts when pre-set values are exceeded,
thus reducing companion micro-processor
overhead.
Maskable Interrupt
• Programmable Upper and Lower Thresholds with
Persistence Filter
Enabling a low-power wait-state between RGBC
measurements to reduce average power
consumption.
Power Management
• Low Power — 2.5-μA Sleep State
• 65-μA Wait State with Programmable Wait State Time
from 2.4 ms to > 7 Seconds

Absolute Maximum Ratings
Stresses beyond those listed under “Absolute Maximum
Ratings” may cause permanent damage to the device. These are
stress ratings only. Functional operation of the device at these
or any other conditions beyond those indicated under
“Recommended Operating Conditions” is not implied. Exposure
to absolute maximum rated conditions for extended periods
may affect device reliability.
