ROHM | BH1603FVC-TR

ROHM ambient light sensors incorporate photodiodes with differing junction depths, enabling light processing internally optimized to match the light source.  This results in stable output sensitivity regardless of the light source.  In conjunction to output sensitivity, ROHM incorporates our very own original laser trimming technology utilized for high light detection making ROHM’s ambient light precision 30-50% better than competitor products.

With built-in high accuracy A/D converter, ROHM ambient light sensors ensure precise measurements over a wide range of lighting conditions, from dimly-lit indoor areas to outdoor environments (1 lx steps).

Additionally, ROHM ambient light sensors include a 2 or 3 stage current output gain switching for compatibility with a wide range of brightness levels: H-Gain for mainly dark environments, M-Gain for both dim and bright conditions indoors, and L-Gain for outdoor environments.

Applications include but are not limited to mobile phones, digital cameras, video cameras, PDAs, portable gaming devices, LCD TVs, PDP TVs, car navigation systems, notebook PCs, and other electronics requiring high precision light sensing.
