Visible Light Sensor

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 Microsemis Best Eye, processing that provides a nearly perfect photopic light wavelength response curve. LX1972A provides 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 Microsemi Corporation
