Description
The ADCS-1121 and ADCS-2121
CMOS Monochrome Image
Sensors capture high quality, low
noise images while consuming
very low power. Housed in a new
industry-standard Ceramic
Leadless Chip Carrier (CLCC)
packaging, these parts integrate
a highly sensitive active pixel
photodiode array with timing
control and onboard A/D conversion. Available in either VGA
(640x480) or CIF (352x288)
resolution image arrays, the
devices are ideally suited for a
wide variety of applications.
The ADCS-2121 and ADCS-1121,
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-1121 and ADCS-2121
image sensors deliver unparalleled performance for mainstream imaging applications.
• CIF resolution (352H x 288V)–
ADCS-1121
• 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 variety of lighting
conditions
• Integrated analog-to-digital
converters:
VGA (ADCS-2121): 10 bit, programmable
CIF (ADCS-1121): 8 bit, fixed
• Parallel and serial output
• Automated, dark response
compensation
• Automatic subtraction of column
fixed pattern noise
• Still image capability
• Synchronous serial or UART
interface
• Integrated voltage references
Typical Applications
• Bar code scanner
• Biometrics
• Machine vision
• Optical character recognition
• Surveillance
