com TM ® LX1972 Ambient Light Detector P RODUCTION S PECIFICATION 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 LX1972 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.
High gain current mirrors on the chip multiply the PIN diode photo-current to a sensitivity level that can be voltage scaled with a standard value external resistor.
Output current from this simple to use two-pin device can be used directly or converted to a voltage by placing it in series ...
