PHOTO IC Digital color sensor 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 adjustable in two steps to cover a wide photometric range. Features Applications 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 l Display color adjustment l Various applications involving color detection ■ A b s o lu te m a x im u m ra tin g s ( Ta = 2 5 ° C ) P a ra m e te r S u p p ly v o lta g e L o a d c u rre n t P o w e r d is s ip a tio n O p e ra tin g te m p e ra tu re S to ra g e te m p e ra tu re S ym bol V dd Io P Topr T s tg V a lu e -0 .3 to 6 ±1 0 100 -2 0 to + 8 5 -4 0 to + 8 5 U n it V mA mW °C °C ■ E le c tric a l a n d o p tic a l c h a ra c te ris tic s (Ta = 2 5 °C , V d d = 5 V, T g = 1 0 0 m s , A lig h t s o u rc e , u n le s s o th e rw is e n o te d ) P a ra m e te r A c tiv e a re a s iz e E ffe c tiv e a c tiv e a re a S p e c tra l re s p o n s e ra n g e P e a k s e n s itiv ity w a v e le n g th S u p p ly v o lta g e C u rre n t c o n s u m p tio n P h o to s e n s itiv ity In c id e n t lig h t p o w e r (C o n v e rs io n v a lu e in A lig h t s o u rc e ) D a rk o u tp u t In p u t h ig h le v e l In p u t lo w le v e l In te g ra tio n tim e H o ld tim e R e a d o u t c lo c k p e rio d R e a d o u t p u ls e w id th (p o s itiv e ) R e a d o u t p u ls e w id th (n e g a tiv e ) S ym bol C o n d itio n A ll e le m e n ts (9 × 9 e le m e n ts ) P e r 1 c o lo r, H ig h ra n g e B lu e λ G re e n Red B lu e λp G re e n Red V dd Id d D a rk s ta te , n o lo a d S bl B lu e , L o w ra n g e S gl G re e n , L o w ra n g e S rl R e d , L o w ra n g e S bh B lu e , H ig h ra n g e S gh G re e n , H ig h ra n g e S rh R e d , H ig h ra n g e Ib l B lu e , L o w ra n g e Ig l G re e n , L o w ra n g e Irl R e d , L o w ra n g e Ib h B lu e , H ig h ra n g e Ig h G re e n , H ig h ra n g e Irh R e d , H ig h ra n g e D a rk T g = 0 .5 s V ih V il Tg t1 t2 t3 t4 t5 tc k tw tc k -tw M in .

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). 2 KPICC0115EB Digital color sensor S9706 ■ Block diagram Range Vdd I/F REGISTER R I/F REGISTER SERIAL CONVERTER Dout G CK I/F GND REGISTER TIMING CIRCUIT B Gate KPICC0110EB ■ Dimensional outline (unit: mm) 4.1 ± 0.2 (INCLUDING BURR) 1.5 ± 0.4 (2 ×) 5˚ 4.0 * 3.9 (2 ×) 10˚ 1.27 1.27 5.0 ± 0.2 (INCLUDING BURR) 4.7 * 0.5 1.5 ± 0.4 4.8 * VISUAL-COMPENSATED FILTER (2.6 × 3.9 × 0.75 t) 2.6 7.0 ± 0.3 0.7 ± 0.3 0.7 ± 0.3 (2 ×) 5˚ 2.0 DEPTH 0.15 MAX. 0.1 ± 0.1 1.8 0.25 0.8 (2 ×) 10˚ Dout Vdd GND Range CK Gate Tolerance unless otherwise noted: ±0.1, 2˚ Chip position accuracy with respect to the package dimensions marked * X, Y≤±0.2 θ≤±3˚ KPICA0060ED Information furnished by HAMAMATSU is believed to be reliable.
