BH1745 Color Sensor

Rohm's digital 16-bit serial output type color sensor IC

Image of Rohm Semiconductor's BH1745 Color SensorBH1745NUC is Rohm’s digital color-sensor IC with I2C bus interface. This IC senses red, green, and blue light (RGB) and converts them to digital values. The high sensitivity, wide dynamic range, and excellent Ircut characteristics make this IC the most suitable to obtain the illuminance and color temperature of ambient light for adjusting LCD backlight of TVs, mobile phones, and tablet PCs. It is possible to detect very wide-range light intensity.
