ADJD-S311-CR999
Miniature Surface Mount RGB Digital Color Sensor
Data Sheet
Description
The ADJD-S311-CR999 is a cost effective, 4 channels
(RGB+CLEAR) digital output sensor in miniature surface-
mount package with a mere size of 2.2 x 2.2 x 0.76mm.
It is a CMOS IC with integrated RGB filters and analog-
to-digital converter front end. This device is designed to
cater for wide dynamic range of illumination level and
is ideal for applications like portable or mobile devices,
which demand higher integration, smaller size and low
power consumption. Sensitivity control is performed by
the serial interface and can be optimized individually for
the different color channel. The sensor can also be used
in conjunction with a white LED for reflective color man-
agement.
Applications
• General color detection and measurement
• Mobile appliances such as mobile phones, PDAs, MP3
players,etc.
• Consumer appliances
• Portable medical equipments
• Portable color detector/reader
Features
• Fully integrated RGB+clear digital color sensor
• 10 bit resolution per channel output
• Built in oscillator/selectable external clock
• Low supply voltage (VDD) 2.5V
• Digital I/O via 2-wire serial interface
• Adjustable sensitivity for different levels of
illumination
• Low power mode (sleep mode)
• Independent gain selection for each channel
• 0°C to 70°C operating temperature
• Industry’s smallest form factor
– CSP 2.2 x 2.2 x 0.76mm
• Lead free package

Detail Description
A hardware reset (by asserting XRST) should be
performed before starting any operation.
Sensor Gain Settings
The sensor gain can be adjusted by varying the number
of capacitors and integration time slot of the sensor
manually through the following registers.
Address
(Hex) Register
6 CAP_RED
7 CAP_GREEN
8 CAP_BLUE
9 CAP_CLEAR
A INT_RED
C INT_GREEN
E INT_BLUE
10 INT_CLEAR

Sensor ADC Output Registers
To obtain sensor ADC value, ‘01’ Hex must be written to
CTRL register. Then, read the value from CTRL register. If
value is 00H, can read sensor output from data register.

Setup Value for Number of Integration Time Slot
The following value can be written to each of the integra-
tion time registers to adjust the gain of the sensor. The
default value after reset for these registers is 00H. These
registers control the number of integration time selected
for each channel. The integration time slot can be varied
from 00H to FFFH. More integration time slot will give
higher sensitivity.
Setup Value for Number of Capacitor
The following value can be written to each of the
capacitor registers to adjust the gain of the sensor. The
default value after reset for these registers is 0FH. These
registers control the number of capacitors selected for
each channel. The maximum selectable capacitor is
16 with the registers starting from 0 (i.e. 0 to 15). Less
capacitor will give higher sensitivity.
