Agilent HDJD-S831-QT333
Color Sensor Module
Data Sheet
Features
• Converts light to R,G,B voltage
output
• Monolithic CMOS IC solution with
integrated R,G,B color filter,
photodiode array, trans-
impedance amplifier in one chip
Description
Applications
• 12x12 photodiode array design
minimizes the effect of
contamination and optical
aperture misalignment
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
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
