Photo IC diode
S9648-100
Plastic package shaped the same as metal package
The S9648-100 photo IC has spectral response close to human eye sensitivity. Two active areas are made on a single chip. 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 the conventional type, the S9648-100 offers lower output fluctuations for light sources producing the same il-
luminance at different color temperatures. The S9648-100 is encapsulated in a plastic package having the same shape as to metal
packages. The shape of the S9648-100 also resembles our 5R type visible sensors (CdS photoconductive cells), so the S9648-100
can be used as a replacement for those visible sensors.
Features
Spectral response close to human eye sensitivity
is attained without using visual-compensated filter.
Operation just as easy to use as a photodiode
Lower output-current fluctuations compared with
phototransistors and CdS photoconductive cells.
Excellent linearity
Low output fluctuations for light sources producing the
same illuminance at different color temperatures
Applications
Energy-saving sensor for TVs, etc.
Light dimmers for liquid crystal panels
Various types of light level measurement
