www.DataSheet4U.com TM ® LX1972A Ambient Light Detector P RODUCTION D ATA S HEET DESCRIPTION KEY FEATURES ƒ Near Human Eye Spectral Response ƒ Very Low IR Sensitivity ƒ Highly Accurate & Repeatable Output Current vs. Light ƒ Scalable Output Voltage ƒ Temperature Stable ƒ Integrated High Gain Photo Current Amplifiers ƒ No Optical Filters Needed APPLICATIONS The LX1972A is a low cost silicon light sensor with a spectral response that closely emulates the human eye. Patented circuitry produces peak spectral response at 580nm, with an IR response less than ±5% of the peak response, above 900nm. The photo sensor is a PIN diode array with Microsemi’s Best Eye™ processing that provides a nearly perfect photopic light wavelength response curve.
