Analog Devices, Inc. (NYSE: ADI), a global leader in high-performance semiconductors for signal processing applications, has received an EDN Magazine 2009 Innovation of the Year Award in the “Analog Front End IC” category for its ADAS1128 current-to-digital converter for CT (computed tomography) scanners. ADI was honored recently at the 20th Annual EDN Innovation Awards ceremony held April 26 in San Jose, Calif.
Analog Devices products also were named finalists in two other categories: “Accelerometers” for the ADXL345 three-axis digital iMEMS® accelerometer for motion sensing; and “Analog: Converters” for the AD9789 14-bit TxDAC® transmit DAC (digital-to-analog converter) for cellular base stations.
“The ADAS1128 was developed by working in close partnership with our CT scanner customers and gaining a deep understanding of their most up-to-date performance requirements.” “Innovation has continued aggressively throughout the economic downturn, as evidenced by EDN's 20th annual Innovation Award winners,” said Rick Nelson, EDN’s editor-in-chief. “Thirty products won out over more than 130 finalists in very competitive categories. ADI’s ADAS1128 current-to-digital converter is a prime example of what key innovators can accomplish.”
Winner - Analog Front End: The ADAS1128 Current-to-Digital Converter
Analog Devices’ ADAS1128 24-bit current-to-digital converter converts photodiode array signals into digital signals. The product has 128 data conversion channels, provides an increase in speed from 6 kSPS (kilosamples per second) to 20 kSPS and supports four times more channels (128 versus 32) than any other integrated converter solution. This level of performance and integration means higher imaging resolution and a 50 percent reduction in system cost.
The ADAS1128 replaces previous converter-based technology having low levels of channel integration. The product integrates a 24-bit resolution ADC (analog-to-digital converter) with 128 simultaneously sampled data converter channels, selectable sample rates up to 20kSPS, and on-chip temperature sensor and reference buffer into a 1 cm2 single-chip solution. The ADAS1128 consumes less than half the power of other solutions (4.5 mW/channel versus 10 mW/channel at full speed). It also offers superior overall performance specs, such as no charge loss, more choices of full scale ranges, and ultra-low noise (down to 0.4 fC for low-dose X-ray systems).

“The ADAS1128 was developed by working in close partnership with our CT scanner customers and gaining a deep understanding of their most up-to-date performance requirements,” said Patrick O’Doherty, vice president, Healthcare Group, Analog Devices. “ADI is honored to be acknowledged by EDN Magazine’s readers and editorial team for the development of this breakthrough current-to-digital converter technology, which enables high slice count CT systems to capture real-time moving images – such as a beating heart – with a high degree of accuracy and detail.”
Finalist - ADXL345 Three-Axis Digital Accelerometer
Developed specifically for energy-constrained portable consumer products, the ADXL345 three-axis digital iMEMS® (integrated micro-electro-mechanical systems) accelerometer is the lowest-power device in its class, achieving an 80 percent power savings compared to competing three-axis inertial sensors. The ADXL345 also incorporates an on-chip ADC (analog-to-digital converter) that simplifies hardware configurations in wireless handsets, personal navigation devices and other mobile applications.

Finalist - AD9789 14-Bit TxDAC® Transmit DAC
Analog Devices’ AD9789 14-bit TxDAC transmit DAC offers an unmatched combination of usable bandwidth and effective dynamic range, shortening time-to-market for DOCSIS-III cable-infrastructure designs using low-cost FPGAs. The AD9789 features ADI’s proprietary Mix-Mode™ super-Nyquist architecture, which supports high-fidelity digital synthesis of RF (radio frequency) signals up to 3.6 GHz. The combination of best-in-class bandwidth and dynamic range with a direct-to-RF core allows broadband equipment designers to use a single transmit-DAC architecture for multiple communications standards while eliminating an off-chip mixer and low-pass filter to reduce design complexity, cost, size, and power.
