| AMI Semiconductor AMIS-74980X Ambient Light Sensor Key Features * * * * Small, integrated solution Approximates human eye response Reports multi-level ambient light intensity Flexible design - Large dynamic range - User programmable integration time - Analog output options - Digital output options (16-bits): SMBus, IC Programmable - based on application Low power design Flicker filtering (fluorescent 50Hz - 60Hz) Standard CMOS process technology Single, two or tri-color (second generation) diode sensors for different accuracies AMIS-74980X Ambient Light Sensor Feature Sheet * * * * * Product Description The AMIS-74980X is a wide dynamic range light sensor with an analog or digital output. There are several versions of the analog output; one with 1uA current output at 1000lux all the way to 1mA at 1000lux. The digital output version has a built-in 16-bit ADC with a 2wire SMBus or I2C digital interface. The sensor employs AMI Semiconductor's proprietary CMOS image sensing technology which provides low noise and high dynamic range output signals and a light response similar to the response of the human eye. Application Information The AMIS-74980X is primarily used in ambient light detection applications, such as a displays back control, where adjustments are made to display brightness or contrast based on the brightness of the ambient light, as perceived by the human eye. Conventional SI detectors respond too strongly to infrared light - a large component of incandescent lighting - preventing natural human eye response. The AMIS-74980X effectively filters infrared light through proprietary techniques providing human eye response.
