The BH1745NUC is a digital color sensor IC that senses and converts the red, green, and blue components of light into digital values. High sensitivity, wide dynamic range, and excellent IR cut characteristics make it ideal for obtaining the illuminance and color temperature of ambient light with high accuracy over a wide range of light intensities (0.005 to 40K lx), under different light sources, and even with dark optical windows, providing superior performance in a variety of environments.

FEATURES

  • Excellent IR removal rate results in high-accuracy RGB component acquisition
  • Enables usage even with dark optical windows
  • Supports color temperature calculation under different light sources
  • I2C bus I/F

APPLICATIONS

  • Smartphones and tablets
  • Cameras
  • LCD TVs
  • Ambient light control (dimming)
  • Color management in industrial processes
