Digital color sensor
S11012-01CR
12-bit digital output
The S11012-01CR is a digital color sensor sensitive to red (λ=615 nm), green (λ=540 nm) and blue (λ=465 nm) regions of the
spectrum. Detected signals are serially output as 12-bit digital data. Built-in three 12-bit registers allow simultaneous measurement
of RGB three colors. Sensitivity level is adjustable in two steps to cover a wide photometric range.

Various applications involving color detection
01 ^Feature
12-bit digital output
Light signals detected by the photodiode are amplified and convert-
ed into 12-bit digital signals. An amplifier is also formed for each of
the RGB photodiode elements arrayed in the mosaic pattern, allow-
ing simultaneous accurate measurement of the RGB components of
incident light.
02 ^Feature
Simultaneous measurement of RGB three colors
The photodiode consists of 9 × 9 elements arrayed in a mosaic
pattern. Each element has an on-chip filter that it sensitive to one
color of light, either red (λp=615 nm), green (λp=540 nm) or blue
(λp=465 nm).
