Description
Agilent 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
Agilent 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.
