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.

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

With accurate internal gain amplifiers,
design complexity and cost are greatly
reduced.
