DESCRIPTION
KEY FEATURES Near Human Eye Spectral Response Very Low IR Sensitivity Highly Accurate & Repeatable Output Current vs. Light Scalable Output Voltage Temperature Stable Integrated High Gain Photo Current Amplifiers No Optical Filters Needed
APPLICATIONS
The LX1974 is a low cost silicon light sensor with spectral response that closely emulates the human eye. Patented circuitry produces peak spectral response at 520nm, with IR response less than ±5%, of the peak response, above 900nm. The photo sensor is a PIN diode array with a linear, accurate, and very repeatable current transfer function.
