S9066-01, S9067-01 photo ICs have spectral response close to human eye sensitivity. Two active areas are made on a single chip. One is for
detecting light in the visible to near infrared range and the other is only sensitive to near infrared light and used for output signal correction.
Almost only the visible range can be measured by finding the difference between the two output signals in the internal current amplifier circuit.
Compared to previously available devices, these photo ICs offer lower output fluctuations for light sources producing the same illuminance at
different color temperatures.
Features
l Spectral response close to human eye sensitivity
is attained without using visual-compensated filter.
l Operation just as easy to use as a photodiode
l Large output current equivalent to phototransistors
l Lower output-current fluctuations
l Excellent linearity
l Low output fluctuations for light sources producing the
same illuminance at different color temperatures
Applications
l Energy-saving sensor for TVs, etc.
l Light dimmers for liquid crystal panels
l Cellular phone backlight dimmers
l Various types of light level measurement
