ADCS-2120

Agilent CMOS Monochrome Image Sensors ADCS-1120 (CIF) and ADCS-2120 (VGA) Product Brief Features • High quality, low cost CMOS Image Sensors VGA resolution (640H x 480V) – ADCS-2120 CIF resolution (352H x 288V) – ADCS-1120 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 conversion. 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 endproduct 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 All images on this product sheet were produced by Agilent Technologies’ sensors and processors. Typical Electrical Specifications Part Number Pixel size Maximum Clock Rate Effective Sensor Dynamic Range Effective Noise Floor Dark Signal [1] ADCS-2120 (VGA) 7.4 x 7.4 µm 25 MHz (VGA) 65 dB (VGA) 43 e270 e-/s 1.6 V/(Lux-S) 38% 1.22V 70,115 e17 mV/e1 – 40 (8 bit resolution) 42% 0.5 µsec minimum, 0.5 µsec increments 3.3V, -5%/+10% 3.6V 3.6V 150 mW operating, 150 µW standby 200 mW operating, 3.3 mW standby 1/3” -5 to +65°C -40 to +125°C ADCS-1120 (CIF) 7.4 x 7.4 µm 32 MHz (CIF) 61 dB (CIF) 43 e270 e-/s 1.6 V/(Lux-S) 38% 1.22V 70,115 e17 mV/e1 – 40 (8 bit resolution) 42% 0.5 µsec minimum, 0.5 µsec increments 3.3V, -5%/+10% 3.6V 3.6V 150 mW operating, 150 µW standby 200 mW operating, 3.3 mW standby 1/4” -5 to +65°C -40 to +125°C Sensitivity [2,3] Peak Quantum Efficiency [1,2,3] Saturation Voltage Full Well Capacity Conversion Gain [2] Programmable Gain Range Fill Factor Exposure Control Supply Voltage Absolute Max.
