TCS34715 Color Sensor

Color light-to-digital converter Vdd I²C


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.

Key Features

  • 1M:1 dynamic range
  • Four independent analog-to-digital converters
  • A reference-channel for Color Analysis (Clear channel photo-diode)
  • Programmable interrupt function
  • Area efficient 2mm x 2.4mm Dual Flat no-lead (FN) package

Key Benefits

  • Enables accurate color and ambient light sensing under varying lighting conditions
  • Minimizes motion / transient errors
  • Clear-Channel provides a reference allows for isolation of color content  
  • Reduces micro-processor Interrupt  overhead
  • Reduces board space requirements while simplifying designs
