Trixell, a long time collaborator of Analog Devices, chose the AD7626 PulSAR ADC because it meets the speed, precision, power, package-size and price requirements of our end-system designs.
NORWOOD, Mass. (PRWEB) June 30, 2008
ADI's AD7626 PulSAR ADC achieves a new level of 16-bit data capture performance, with best-in-class 15-bit ENOB (effective number of bits) and 10-MSPS (million samples per second) throughput, which is 2.5 times faster than other SAR ADCs. Unlike other ADCs, which operate at much lower speeds or reach higher sample rates by increasing power consumption and trading off ac and dc performance, the AD7626 PulSAR ADC has a 92-dB SNR (signal-to-noise ratio) that is 8 dB (1.3 bits) better than any ADC, regardless of architecture.
"For high-end X-ray imaging devices, accuracy and throughput are key performance vectors that enable higher image quality and improved frame rates," said Stephane Rossignol, Electronics and ASIC group manager, Trixell, a joint venture company of Thales Electron Devices, Philips Medical Systems and Siemens Healthcare and a leading developer radiological imaging flat panel detectors. "Trixell, a long time collaborator of Analog Devices, chose the AD7626 PulSAR ADC because it meets the speed, precision, power, package-size and price requirements of our end-system designs."
"From factory automation systems that boost productivity to sensitive medical imaging equipment that quickly and non-invasively scan patients, virtually all manufacturers want to push the speed barrier while holding a firm line on data accuracy," said Leo McHugh, product line director, precision signal processing, Analog Devices. "The AD7626 takes a dramatic jump forward in terms of sampling rates, while delivering linearity performance that rivals converters with much lower throughputs."
For applications that don't require full 10-MSPS data rates, the AD7626 can be easily multiplexed. Some medical imaging devices, for example, could use the AD7626 in a two-channel configuration where each channel operates at 5 MSPS. This would allow the system designer to lower materials costs by reducing data converter component count by 50 percent—while still maintaining speeds that are 25 percent faster than existing solutions.
"Data conversion technology determines the quality of the user experience in applications as diverse as ultrasound imaging to digital TV, mobile phones and other consumer goods," said Susie Inouye, research director at Databeans Inc., a leading semiconductor research firm. "Because there is such a variety of end uses, however, there is no single specification that defines a good data converter. OEMs today need semiconductor design partners to solve tough signal processing challenges, and ADI engineers are among the best at bridging the analog and digital worlds through delivering the right converter for the problem."
AD7626 10-MSPS ADC Features Smallest Size, Lowest Power in its Class
Housed in a compact 5 mm × 5 mm QFN (quad flat no-lead) package that is 70 percent smaller than competing offerings, the AD7626 consumes just 130 mW of power, which even at its highest sample rate is 15 percent lower than other ADCs in its class. The AD7626 also uses a self-clocked low-voltage differential serial (LVDS) bus that provides a very-low-noise interface and reduces the number of external components required to address board-level noise concerns.
AD7625 6-MSPS ADC Further Extends ADI's PulSAR Portfolio
Also today, Analog Devices introduced the AD7625 16-bit PulSAR ADC, which operates at 6 MSPS and expands the PulSAR family to 15 devices with speed options ranging from 1 MSPS to 10 MSPS and dynamic range of 16 bits to 18 bits. Analog Devices' extensive PulSAR family is based on an ADC architecture that provides the added advantage of zero data-latency, which is critical in precision data acquisition systems.
