HDJD-S833-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 VBOUT, 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 1 Sensor IC Block Diagram GS (1:0) RF VDD5 VOLTAGE REGULATOR CF – + GND VDD3 VROUT TRANSIMPEDANCE AMP GS (1:0) RF CF GSRED (0:1) GSGRN (0:1) RED GAIN SELECTION – + VGOUT TRANSIMPEDANCE AMP GREEN GAIN SELECTION GS (1:0) RF CF GSBLUE (0:1) BLUE GAIN SELECTION – + VBOUT TRANSIMPEDANCE AMP Absolute Maximum Ratings[1,2] Parameter Symbol Min.
