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 VR
OUT
, VG
OUT
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.
