| 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 ... |
| 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 levels.
The LX1977 integrates a 12-bit SigmaDelta A/D converter that converts the ALS photodiode outpu... |
