S9066-211SB S9067-201CT
Spectral response close to human eye sensitivity
The S9066-211SB, S9067-201CT photo ICs have spectral response close to human eye sensitivity. Two photosensitive 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.

*1: Power dissipation decreases at a rate of the following rate above Ta=25 °C.
S9066-211SB: 3.3 mW/°C, S9067-201CT: 2.0 mW/°C
*2: When there is a temperature difference between a product and the surrounding area in high humidity environment, dew condensation
may occur on the product surface. Dew condensation on the product may cause deterioration in characteristics and reliability.
Note: Exceeding the absolute maximum ratings even momentarily may cause a drop in product quality. Always be sure to use the
product within the absolute maximum ratings.
