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
(640x480) or CIF (352x288)
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.
• High frame rates for digital video
VGA: 15 frames/second
CIF: 30 frames/second
• High sensitivity, low noise design–
Ideal for capturing high-quality
images in a wide variety of lighting
conditions
• Integrated Analog-to-Digital
Converters
VGA (ADCS-2120): 10 bit, programmable
CIF (ADCS-1120): 8 bit, fixed
• Parallel and serial output
• Synchronous serial or UART
interface
• Automated, dark response
compensation
• Still image capability
Typical Applications
• Biometrics
• Surveillance
• Machine vision
• Bar code scanners
