\r\nFirst 12-Bit, 40-MSPS AFE for CMOS Imagers \r\n
\r\n\r\n
\r\nThe AD9821 is the industry’s first 12-bit, 40-MSPS AFE. The device is designed to interface with CMOS imagers used in applications for which image quality is essential, such as medical imaging, microscopy, industrial/machine vision, digital photography, biometrics, and automatic inspection equipment. An alternative to component-based solutions using several ICs performing discrete functions, the AD9821 provides all the functionality needed to digitize an image from a CMOS image sensor on a single, integrated chip. The AD9821 features a 12-bit, 40-MSPS ADC that interfaces with high-speed CMOS sensors via a differential sensor input. It includes a low-noise optical black clamp and a 0-to-36 dB, 10-bit programmable gain amplifier. The AD9821 dissipates only 150 mW, enabling longer battery life in portable applications. \r\n

\r\nBest Performance for CCD Imagers \r\n
\r\n\r\n
\r\nThe AD9845B is the industry’s highest performance 12-bit, 30-MSPS AFE and is designed for high-speed, high-resolution CCD (charge-coupled devices) imaging applications, such as scientific and industrial imaging devices, as well as digital still cameras and camcorders. Addressing designer demand for higher resolution images produced at faster bit rates, the AD9845B improves upon the standard AFE resolution of 10 bits, delivering image quality 4 times higher and 1.5 times faster than any standard AFE on the market. In addition, the AD9845B features an integrated 6-bit resolution PxGA® (pixel gain amplifier) that enables better image quality, by allowing gain to be finely tuned to fit the image. \r\n

\r\nThe AD9845B includes a 12-bit 30-MSPS ADC (analog-to-digital converter), a 30-MSPS CDS (correlated double sampler), a 4 dB plus/minus 6 dB 6-bit PxGA®, and a 2 dB to 36 dB 10-bit VGA (variable gain amplifier). It also provides an input clamp, black level clamp, and input modes for processing analog video signals. Its internal registers are programmed through a 3-wire serial digital interface. Programmable features include gain adjustment, black level adjustment, input confirmation and power-down modes. The AD9845B operates from a single 3 V power supply and typically dissipates 153 mW.“;0;60;4;“admin“;““;0;““;0;0;0;0;0
