The LX1977 is a CMOS based Ambient Light Sensor (ALS) with an I2C compatible SMBus interface.

adjustable input range and gain. The LX1977 has a spectral response that emulates the human eye. Specially designed circuitry produces peak spectral response at 555 nm, with IR response less than 10% above 810 nm. Input dynamic range of this device is adjustable via SMBus command. It can be set to either 0 ~ 500 lux, 0 ~ 1000 lux, 0 ~ 2500 lux or 0 ~ 5000 lux. ALS internal compensation ensures photodiode dark current are at very low levels, providing high output accuracy at low ambient light le.
