ambient light sensorEverlight Electronics introduced an Ambient Light Sensor (ALS) product family that meets the requirements for power management solutions for the display backlighting of mobile appliances such as mobile phones, notebooks and PDAs. The sensors combine a photodiode and a current amplifier IC in one package to save power for backlighting displays in mobile appliances by adjusting the backlight brightness depending on the ambient light. To ensure accurate measurement, the spectral response of the ambient light sensor corresponds to that of the human eye. The Everlight ALS are current output types which offer a high output linearity across a wide illumination range and a low sensitivity variation across various light sources. The ALS can be operated within a supply voltage range from 1.8 V to 5.5 V and in a temperature range from -40°C up to 85°C.
