The digital CLS is a low power, high sensitivity, Color light sensor with an I2C interface. This color sensor senses red, green, blue, white (RGBW) and infrared light and converts them to digital values. The RGBW sensor is designed to reject IR in light sources allowing the device to operate in environments from sunlight to dark rooms. The integrating ADC rejects 50Hz and 60Hz flicker caused by artificial light sources. A selectable range allows the user to optimize sensitivity suitable for the illuminance and color temperature of ambient light for adjusting LCD backlight of TV, mobile phone and tablet PC. The digital CLS supports hardware and software user programmable interrupt thresholds.
