TCS34717 Color Sensor

Color light-to-digital converter 1.8V I²C


  • 1M:1 dynamic range
  • Four independent analog-to-digital converters
  • A reference channel for color analysis (clear channel photodiode)
  • Programmable interrupt function
  • Area efficient 2mm x 2.4mm Dual Flat no-lead (FN) package


  • Enables accurate color and ambient light sensing under varying lighting conditions
  • Minimizes motion/transient errors
  • Clear channel provides a reference which allows for isolation of color content
  • Reduces microprocessor interrupt overhead
  • Reduces board space requirements while simplifying designs

General description

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. This data is transferred via an I2C to the host.

Not Recommended for New Designs!
