Agilent CMOS Monochrome
Image Sensors ADCS-1120 (CIF)
and ADCS-2120 (VGA)
Product Brief
Description
The ADCS-1120 and ADCS-2120
CMOS Image Sensors capture high
quality images while consuming
very low power. These parts
integrate a highly sensitive active
pixel photodiode array with timing
control and onboard A/D conver-
sion. Available in either VGA
(640x 480) or CIF (352x 288)
resolution image arrays, the
devices are ideally suited for low
light environment.
The ADCS-2120 and ADCS-1120,
when coupled with Agilent's
HDCP family of image-processors,
provide a complete imaging
system to enable rapid end-
product development. Designed
for low-cost consumer electronic
applications, the ADCS-2120 and
ADCS-1120 sensors deliver
unparalleled performance for
mainstream imaging applications.
