Product details

Description

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

This device is ideal for controlling display back lighting systems of low cost consumer products such as TV, portable computers, handheld devices, or medical devices.

Features

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.
