ROHM’s ambient light sensors (analog and digital) feature optical characteristics close to the human eye, enabling automatic backlight adjustment in displays for lower power consumption and optimum visibility. The latest digital sensor IC, BH1726NUC, is most suitable for obtaining ambient light data for adjusting LCD and backlight power of TV and mobile phone. It is capable of detecting a very wide range of illuminance. The latest analog sensor IC, BH1682FVC, has wide illuminance detection range and is suitable for the application of display brightness control. The output is proportion to logarithm of illuminance.
