Analog Devices (ADI), a leading provider of high performance semiconductors used in signal processing applications was awarded the 2009 Innovation of the Year Award in the category Analog Front End IC for its current to digital converter, the ADAS1128 used in computer tomography (CT) scanners.
The award winning event was held in San Jose, California on April 26, 2010 at the 20th Annual EDN Innovation Awards.

ADI was also a finalist in two other product categories –the ‘Accelerometers’ category for its ADXL345 three-axis digital iMEMS accelerometer used for motion sensing and the ‘Analog Converters’ category for its AD9789 14-bit TxDAC transmit DAC (digital-to-analog converter) used in cellular base stations.
The ADAS1128 is a 24-bit based current to digital converter that transforms the photodiode array signals to digital signals. It offers 128 channels for data conversion, an increase in speed to 20 kSPS from 6 kSPS and is capable of supporting four times more channels when compared to various other integrated converter solutions. This integration and performance level implies a 50% system cost reduction and higher imaging resolution.
It replaces earlier converter-enabled technology that has low channel integration levels. It combines 24-bit resolution analog to digital converter (ADC) and simultaneous 128 sampled data converter channels, on-chip temperature sensor, reference buffer and selectable sample rates, the maximum rate of which is 20kSPS in a single chip solution measuring a mere 1 cm2. Compared to other solutions it consumes less than 50% of power and provides better overall performance specifications that include more options for full scale ranges, no charge loss and very low noise that is as low as 0.4 fC when applied for the low-dose X-ray systems.
The ADXL345 Three-Axis Digital Accelerometer was developed particularly for consumer products that are energy-constrained. It is the least priced device in its category and provides 80% savings in power consumption when compared to other three-axis inertial sensors.
The list 14-Bit TxDAC Transmit DAC provides the best effective dynamic range and usable bandwidth combination and helps to reduce the time to market for those DOCSIS-III type cable infrastructure designs that utilize low-priced FPGAs. It features the Mix-Mode super-Nyquist architecture, a proprietary architecture of ADI. This architecture is able to support high fidelity digital synthesizing for RF signals to a maximum of 3.6 GHz.
