S9706
12-bit digital output
S9706 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 adjust-
able in two steps to cover a wide photometric range.
Features
l 12-bit serial output
l Low voltage (3.3 V) operation
l Simultaneous measurement of RGB three colors
l 2-step sensitivity switching (sensitivity ratio of 1:9)
l CMOS monolithic photo IC
l No external components required
Applications
l Display color adjustment
l Various applications involving color detection
