- AD9978A and ADDI7004 HD image signal processors combine image signal conditioning circuitry, a 14-bit ADC, and precision timing core to enable high-speed digital imaging.
NORWOOD, Mass.--As medical, industrial and scientific markets increasingly adopt high-definition (HD) image acquisition systems, designers of such systems must confront a host of signal-processing complexities in order to accurately capture and record high-resolution images. To address these challenges, Analog Devices, Inc. (ADI), the leading provider of AFE (analog front end) technology in digital imaging applications and the leading provider of data-conversion technology, today introduced two high-performance, highly integrated 14-bit HD image signal processors: the 75 MSPS dual-channel AD9978A--the industry''s fastest-- and the 72 MSPS quad-channel ADDI7004. These single-chip solutions enable designers to create multi-channel CCD (charge-coupled device) or CMOS (complementary metal-oxide semiconductor) HD image acquisition systems that can deliver the degree of clarity, visibility and accuracy needed for today''s high-resolution requirements.
Many leading manufacturers of digital still cameras, camcorders, scanners and other imaging systems depend on Analog Devices to deliver the highest performance products with the lowest power dissipation available. Analog Devices'' 75 MSPS dual-channel AD9978A and 72 MSPS quad-channel ADDI7004 HD image signal processors enable the high-resolution, high-speed sampling of signals from advanced image sensors, while consuming very little power-280 mW (milliwatts) and 530 mW, respectively.
"Until today, high-performance imaging system designers were forced to use multiple high-power components to sample image signals at HD rates," said Stuart Boyd, product line director, Digital Imaging Systems, Analog Devices. "By integrating high-performance signal conditioning circuitry, a 14-bit data converter, and a precision timing core into a single HD image acquisition solution, designers can achieve an unequalled combination of speed and accuracy in high-speed, high-resolution digital imaging systems, while eliminating the power dissipation limitations that restrict portability and increase design cost."
