C OM The LX1970 is a new technology light sensor with spectral response that emulates the human eye.
This device is ideal for monitoring ambient light for brightness control systems in flat panel displays.
It has a unique photo diode arrangement (patents pending) with a peak response at 520 nm while sharply attenuating both ultra violet and infrared wavelengths.
The photo sensor is a PIN diode array with an accurate, linear, and very repeatable current transfer function.
Photo current is multiplied by integrated high gain amplifiers and is made available at two output pins; one a current source and the other a current sink.
These currents can easily be converted to voltage by adding a single resistor at either or both outputs.
Voltage gain is determined by the resistor value typically in the 10KΩ to 50KΩ range.
With accurate inte...
