www.DataSheet4U.com TM ® LX1973A Automotive Light Sensor P RODUCTION D ATA S HEET DESCRIPTION KEY FEATURES Nearly Perfect Best Eye™ Human Eye Spectral Response 25C Dark Current <0.005 lux 5 Decades Compressed Output 10% Accuracy Over Temperature Scalable Output Voltage No Optical Filters Needed The LX1973A is a wide dynamic range light sensor with a very low dark current that is optimized for sensing low level light signals that typically occur under dark or darkening outdoor ambient lighting. The LX1973A has been optimized for automotive systems such as headlamp brightness control or rear view mirror contrast control. Its radical (fractional exponent) response when interfaced with an 8 bit DAC can detect levels down to 0.001 lux or levels as high as 500 lux.
