Color sensor S9706 12-bit digital output The 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 adjustable in two steps to cover a wide photometric range.

The photodiode photosensitive area used to detect light differs depending on which sensitivity mode is selected (high sensitivity mode: 9 × 9 elements, low sensitivity mode: 3 × 3 elements in center). Mode High sensitivity Low sensitivity Effective photosensitive area* 9 × 9 elements 3 × 3 elements * The photosensitive area of S9706 consists of 9 × 9 elements in a mosaic pattern. The effective photosensitive area changes depending on which sensitivity mode is used, “high” or “low”, as explained below. · High sensitivity mode: 9 × 9 elements · Low sensitivity mode: 3 × 3 elements in center 132 110 Pin no. 1 side Pin no. 6 side 110 Range High Low Details of photosensitive area (unit: μm) 132 Sensitivity setting 3 × 3 elements in low sensitivity mode 9 × 9 elements in high sensitivity mode Pin no. 3 side Pin no. 4 side Note: Spaceing between elements is light-shielded.

(2) Select the desired sensitivity with the Range terminal. (3) Set the Gate terminal from “Low” to “High”, to start integrating the light intensity. (4) After the desired integration time (tg) has passed, set the Gate terminal from “High” to “Low” to end the light intensity integration. (5) Measurement data is output from the Dout terminal by inputting 36 CK pulses to the CK terminal. Note 1: A total of 36 CK pulses are required to read out 3-color measurement data. Red data is output by the first 12 pulses, green data by the next 12 pulses, and blue data by the last 12 pulses. Measurement data is output from the LSB side. Note 2: Measurement data changes at the CK pulse rising edge. Note 3: Do not switch the Range terminal during integration time (tg).
