Analog Devices, Inc., (NASDAQ: ADI), the leading provider of data conversion technology* and longtime collaborator to the medical imaging industry, today introduced a highly integrated digital X-ray analog front end (AFE) with the industry’s lowest noise performance in multiple power-mode options, and the highest image quality. The 256-channel ADAS1256 digital X-ray AFE is the industry’s first single-chip solution to integrate the complete charge-to-digital conversion signal chain by incorporating low-noise programmable-charge amplifiers, correlated double-sampling circuitry and 16-bit A/D converters. With a noise figure of an equivalent charge of 560 electrons at a 2-picocoulomb full-scale range, the ADAS1256 enables high resolution digital X-ray images while reducing patient exposure to X-ray dose. The ADAS1256 has multiple functional power modes ranging from 1-mW/channel to 3-mW/channel, allowing manufacturers to address a wide range of digital X-ray modalities including portable radiology and mammography as well as high speed fluoroscopy and cardiac imaging.
