| HDJD-S831-QT333 Color Sensor Module Data Sheet Description Avago Color Sensor is a high performance, small in size, cost effective light to voltage converting sensor. The sensor combines a photodiode array and three trans-impedance amplifiers in a single monolithic CMOS IC solution. With Red (R), Green (G), and Blue (B) color filters coated over the photodiode array, the sensor converts RGB light to analog voltage outputs, denoted by VROUT, VGOUT and VB OUT, respectively. The sensor is driven by a single 5 V supply and incorporates an internal 5 V to 3.3 V voltage regulator. The color sensor module consists of a color sensor packaged in a 5 x 5 x 2 [mm] surface mount QFN-16, flat flexible cable connector and a decoupling capacitor mounted on a PCB. Applications Avago Color Sensor is ideal for open-loop color identification and closed-loop color point control. The spectral sensitivity response of the sensor is optimized for RGB-LED backlight applications. The sensor has good detection ability in light output chromaticity drift, when used with closed-loop feedback controller, manages to bring the backlight system to realize good du'v' performance. Potential applications include white point control in emissive display, environmental lighting, color control in industrial processes, and many more.

Theory of Operation The integral R,G,B color filters on the photodiode array detect the R,G,B components of the light falling on the sensor. The photodiode converts the R,G,B light components into photocurrents. The integrated transimpedence amplifiers for R,G,B components then convert the photocurrent to analog voltage outputs. The voltage output of each R,G,B channel increases linearly with increasing light intensity. 4 Sensor IC Block Diagram GS (1:0) CF RF VDD5 VOLTAGE REGULATOR GND - + TRANSIMPEDANCE AMP RF CF GS (1:0) VROUT VDD3 GSRED (0:1) RED GAIN SELECTION - + TRANSIMPEDANCE AMP RF CF GS (1:0) VGOUT GSGRN (0:1) GREEN GAIN SELECTION GSBLUE (0:1) BLUE GAIN SELECTION - + TRANSIMPEDANCE AMP VBOUT Absolute Maximum Ratings[1,2] Parameter Supply Voltage Storage Temperature Operating Temperature Human Body Model ESD Rating Symbol VDD5 TS TA ESDHBM Min. 4.5 -20 -20 Max. 5.5 85 85 2 Unit V C C kV Reference to JESD22-A114-B Notes Notes: 1.
