Digital color sensor
S11059-02DT/-03DS
I²C interface-compatible color sensor
The S11059-02DT/-03DS is a digital color sensor that supports the I²C (inter-integrated circuit) interface. It is sensitive to
red (λ=615 nm), green (λ=530 nm), blue (λ=460 nm), and infrared (λ=855 nm) light, and outputs detected results as 16-
bit digital data for each color. The photodiode for each color is automatically switched sequentially to perform measurements.
The sensitivity and integration time can be adjusted so that light measurements can be performed over a wide range.
Features
I²C interface compatible
Sequential measurements of red, green, blue, and infrared light
2-step sensitivity switching (sensitivity ratio 1 : 10)
Sensitivity adjustment by setting the integration time
Low voltage (2.5 V or 3.3 V) operation
Low current consumption: 75 μA typ.
With internal infrared-cut filter
Wide dynamic range (Low gain: 1 to 10 klx)
Applications
LCD backlight adjustment for cell phones, notebook PC, etc.
Energy-saving sensor for large-size TV, etc.
