Agilent Technologies CMOS Monochrome Image Sensors ADCS-1121 (CIF), ADCS-2121 (VGA) Product Overview Features • High quality, low cost CMOS image sensors • Industry-standard 32-pin CLCC package • VGA resolution (640H x 480V)– ADCS-2121 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 Image Sensor Specifications Part Number ADCS-2121 (VGA) ADCS-1121 (CIF) Active Pixel Array Resolution Pixel size Maximum Clock Rate Effective Sensor Dynamic Range Effective Noise Floor Dark Signal [1,3] Saturation Voltage Full Well Capacity Conversion Gain [2] Programmable Gain Range Fill Factor Exposure Control Supply Voltage Absolute Max.
