Ambient Light Sensors

Based on a patented dual-diode implementation, the Ambient Light Sensor (ALS) devices approximate the human eye response to light under a variety of lighting conditions. The devices have a wide range of performance allowing accurate ALS measurements in lighting environments ranging from low-light to bright sunlight up to 220K lux. This family of devices is particularly useful for display management dimming or brightness control with the purpose of reducing power consumption, extending battery life, and providing the optimum viewing in diverse lighting conditions.
