Analog Devices Raises the Standards in Precision Data Conversion to Improve Industrial, Medical, and Instrumentation System Performance.

New ADCs Enable Faster, More Accurate Equipment While Reducing Power Consumption and System Size

MUNICH, Germany -- Analog Devices Inc. (NYSE: ADI), a global leader in high-performance semiconductors for signal processing applications, is making new levels of precision data conversion performance available with the introduction of three analog-to-digital converters (ADCs). The new ADCs are designed for industrial, medical, and instrumentation applications that need the speed, accuracy, low-power, integration and small size critical to system design and performance. Designers of precision applications, such as medical imaging devices, data acquisition systems, and vibration analysis equipment, need high performance data conversion devices for successful end products that measure, sense, and process signals with utmost accuracy. ADI's new ADCs deliver significantly better performance in terms of speed, accuracy, power, and size when compared with other currently available converters.

Analog Devices is introducing the following:

* 18-bit 1-MSPS PulSAR[R] ADC - The AD7982 has the best combination of accuracy and power consumption of any available 18-bit ADC, with an industry-best 1-MSPS (million samples per second) sample rate and only 7.5 mW of power dissipation. The new converter delivers an effective resolution of 22.7 bits with an output data rate of 1 kSPS.

* Dual 12-Bit, 5-MSPS, Simultaneous Sampling SAR ADC - The AD7356 SAR (successive-approximation register) ADC features two 5-MSPS cores and is 25 percent faster than competing single-channel 12-bit SAR ADCs. The AD7356 is more than three times the speed of other simultaneous sampling SAR converters in its class.

* 24-bit over-sampling 125-kSPS ADC - The AD7766 features a 125-kSPS sampling rate at 15 mW, providing a 20 percent improvement in speed over competitive devices, while consuming approximately 85 percent less power.

Industry-leading Accuracy and Power: More About the AD7982

The AD7982 ADC consumes just 7.5 mW, which is 95 percent less power than the closest competing 18-bit ADC in its class. The AD7982 also has a significant size advantage, shipping in a 10-pin QFN (quad flat no-lead) package, which is 80 percent smaller than any other 18-bit ADC capable of a 1-MSPS clock rate.

The AD7982 is aimed at industrial and medical equipment such as CT scanners, which, for the first time, allow physicians to capture images of vital organs in a single scan. Older CT scanners rely on less accurate ADCs with higher power consumption, limiting the effective size, or width, of the scanner. In the case of a human heart, the multiple scans needed to render a complete image occur at slightly different points in time, requiring an additional EKG (electrocardiogram) monitor and phase-shifting technology to accurately depict the heart in motion. The size, power and precision advantages of the AD7982 not only improve image quality and medical diagnostic results, but eliminate the need for a second piece of equipment during a CT scanning procedure.

The AD7982 18-bit 1-MSPS PulSAR ADC is sampling now in 10-lead QFN and MSOP (mini small-outline package) packages, with production quantities available in the first quarter of 2007. The AD7982 is priced at $23.00 in 1,000-unit quantities. For more information, visit www.analog.com/pr/AD7982.

Industry's Fastest 12-Bit SAR ADC: More About the AD7356

The AD7356 consumes just 35 mW of power when operating at 5 MSPS. The new device allows users to simultaneously sample two ADC cores to provide a 12-bit result just 167 ns after the sampling instant (or return conversion samples every 200 ns). This means a result can be obtained with every conversion cycle, whereas competing devices have a one-cycle latency that hampers their ability to deliver real-time results to the system processor. The AD7356's dual-core architecture and internal reference allow designers to more tightly integrate their board configurations and save valuable board space.

The low latency and power consumption of the AD7356, combined with higher data throughput, provide a key performance advantage for optical encoders used in high-speed industrial motor controls, where constant measurement of motor functions is needed to maintain precise system operation. The AD7356 also is suited for wide-bandwidth applications, such as adaptive cruise control, an emerging safety feature in automotive platforms that requires rapid and continuous signal conversion to measure vehicle speed and velocity. The new SAR ADC is additionally designed for applications like RFID (radio frequency identification) transceivers, which increasingly are replacing bar code scanners in high-throughput scanning operations that demand accurate, high-speed measurement.

The AD7356 SAR ADC is sampling now in a 16-lead TSSOP (thin-shrink small outline package) with production quantities available in July 2007. The AD7356 is priced at $7.89 in 1,000-unit quantities. For more information, visit www.analog.com/pr/AD7356.

Highest Dynamic Range and Lowest Power in its Class: More About the AD7766

The 24-bit AD7766 has a dynamic range of 108 dB at 125 kHz, 3 dB better than competing devices at the same output data rate. Additionally, the AD7766 has a 1.8 [acute accent]V/C offset drift, reducing the need to recalibrate the device due to temperature fluctuations.

The AD7766 is designed for low-power equipment where small or faint signals must be distinguished in the presence of larger signals, including applications like echolocation, data acquisition and industrial vibration analysis. In sonar equipment, for example, the ADC's best-in-class signal-to-noise ratio (SNR), which is as high as 114 dB at a 31.25-kHz output data rate, allows technicians to identify underwater features at greater distances than was previously possible. In industrial applications such as vibration analysis, the AD7766 can help reduce machinery repair costs and lost production time. A faulty bearing or rotor, for example, will cause tiny changes in the machine's acoustical profile that can be measured using the new ADC's ability to pick small ac signals out of larger background signals. This allows equipment operators to detect imminent failures in mission-critical systems and schedule maintenance before the failure occurs, lowering operating costs and improving overall equipment reliability.

The AD7766 ADC is sampling now in a 16-lead TSSOP with production quantities available in the third quarter of 2007. The AD7766 is priced at $5.95 in 1,000-unit quantities. For more information, visit www.analog.com/pr/AD7766.
