S9648-100
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 nding the difference between the two output signals in the internal current amplier
circuit. Compared to the conventional type, the S9648-100 offers lower output uctuations 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.
