Agilent ADCS-1021, ADCS-2021
CMOS Image Sensors
Data Sheet
Description
The ADCS-1021 and ADCS-2021
CMOS Image Sensors capture
high quality, low noise images
while consuming very low power.
These parts integrate a highly
sensitive active pixel photodiode
array with timing control and
onboard A/D conversion. Avail-
able in either VGA (640x480) or
CIF (352x288) resolution image
arrays, the devices are ideally
suited for a wide variety of
applications.
The ADCS-2021 and ADCS-1021,
when coupled with compatible
image processors from either
Agilent or selected Agilent
partners, provide a complete
imaging system to enable rapid
end-product development.
Designed for low-cost consumer
electronic applications, the
ADCS-2021 and ADCS-1021
sensors deliver unparalleled
performance for mainstream
imaging applications.
ADCS-2021 (VGA) and
ADCS-1021 (CIF) are CMOS active
pixel image sensors with inte-
grated A/D conversion and full
timing control. They provide
random access of sensor pixels,
which allows windowing and
panning capabilities. The sensor
is designed for video conferencing

applications and still image
capabilities. The ADCS family
achieves excellent image quality
with very low dark current, high
sensitivity, and superior anti-
blooming characteristics. The
devices operate from a single DC
bias voltage, are easy to configure
and control, and feature low
power consumption.
