BH1730FVC-TR Datasheet PDF - ROHM Semiconductor

●The BH1730FVC-TR is a Digital Ambient Light Sensor IC for I²C bus interface. This IC is the most suitable to obtain the ambient light data for adjusting LCD backlight power of TV, mobile phone. It is possible to detect very wide range light intensity. (0.008 to 65535 lx ). There are two outputs that peaks of a spectrum response are in visible light (Type0) and in infrared light (Type1). Light source dependency is little by calculating with Type0 and Type1. ( ex. Incandescent Lamp. Fluorescent Lamp. Halogen Lamp. White LED. Sun Light ).The device has adjustable measurement result for influence of optical window.
