Product Description
AMIS-74980x wide dynamic range light sensor with analog digital output. There several versions analog output; with current output 1000lux 1000lux. digital output version built-in 16-bit with 2wire SMBus digital interface. sensor employs Semiconductor's proprietary CMOS image sensing technology which provides noise high dynamic range output signals light response similar response human eye.
Application Information
AMIS-74980x primarily used ambient light detection applications, such displays back control, where adjustments made display brightness contrast based brightness ambient light, perceived human eye. Conventional detectors respond strongly infrared light large component incandescent lighting preventing natural human response. AMIS-74980x effectively filters infrared light through proprietary techniques providing human response.
