Datasheet
Ambient Light Sensor IC Series
Digital 16bit Serial Output Type
Ambient Light Sensor IC
BH1730FVC
General Description
BH1730FVC is a digital Ambient Light Sensor IC with I²C
bus interface. This IC 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.
Features
■ I²C bus Interface
f/s Mode Support, Slave Address "0101001"
■ 2 outputs with peak wavelengths of visible light and
infrared light respectively.
■ Illuminance to digital converter
■ Low current by power down function
■ 50Hz / 60Hz light noise reject function
■ Light source dependency is small by the calculation
using 2 outputs. (e.g. Incandescent lamp, Fluorescent
lamp, Halogen lamp, White LED and Sun light)
■ Built-in interrupt function
■ Sensitivity adjustment function for compensation for
illuminance decrease by optical window
