ADI's 16-bit, 10-msps SAR Analog-to-digital Converter

Beijing, China   (July 3, 2008) - analog devices, Inc. (NYSE: ADI), the world's leading supplier of high-performance signal processing solutions, recently launched a precision 16 bit successive approximation (SAR) analog-to-digital converter (ADC) - ad7626, which makes a new breakthrough in data conversion, provides excellent speed and accuracy, and expands its pulsar ® Product line. In most high-performance industrial and medical devices today, the most important requirement is to maintain data integrity while processing information at high speed. For example, in medical magnetic resonance imaging (MRI) and digital X-ray systems, the speed and accuracy provided by this new pulsar ADC enable medical procedures to be carried out more quickly and effectively, reducing the time of MRI examination and exposure to X-ray radiation.

ADI's ad7626 pulsar ADC refreshes the 16 bit data acquisition performance, has the best 15 bit significant bit (ENOB) and 10-msps sampling rate, and is 2.5 times faster than other SAR ADCs. Other ADCs have low operating rate or need to increase power consumption to achieve high sampling rate, which will affect AC and DC performance. Ad7626 pulsar ADC can provide 92 DB signal-to-noise ratio (SNR), which is 8 dB (1.3 bit) higher than ADC of any other architecture.

Stephane Rossignol, manager of electronics and ASIC Department of trixell company, pointed out: "For high-end X-ray imaging equipment, accuracy and throughput are key performance indicators to achieve higher image quality and improve frame rate. As a long-term partner of ADI, trixell chose ad7626 pulsar ADC because it meets the speed, accuracy, power consumption, package size and price requirements of our terminal system design." Trixell, a joint venture of Thales electronics, Philips Medical Systems and Siemens Healthcare, is a leading developer of radiation imaging flat panel detectors.

Zhou Wensheng, senior industrial and medical business manager of ADI in Greater China, said: "From factory automation systems with rapid productivity growth to sensitive medical imaging equipment that can provide patients with rapid and noninvasive examination, in fact, all manufacturers want to surpass speed barriers while maintaining high data accuracy. The ad7626 significantly improves the sampling rate and provides linear performance comparable to other low rate converters."

For applications that do not require a 10-msps data rate, the ad7626 can be easily multiplexed. For example, some medical imaging devices can use the ad7626 in a dual channel configuration, where the sampling rate of each channel is 5 MSPs, which allows the system designer to reduce the number of converters by half, thus reducing the bill of materials cost, and its speed can still be faster than the existing solutions Cases increased by 25%.

Susie Inouye, research director of databeans Inc., a leading semiconductor research company, pointed out: "Data conversion technology determines the quality of user experience in a wide range of applications from ultrasonic imaging to digital television, mobile phones and other consumer electronic products. Due to the wide variety of terminal applications, it is impossible to define a high-performance data converter through a single index. Today's original equipment manufacturers (OEMs) We need to solve the difficult signal processing challenges with the assistance of semiconductor design partners. ADI's engineers have rich experience in analog and digital fields and can provide users with the most suitable converters. "

The ad7626 10-msps ADC has the smallest size and lowest power consumption of its kind

5 mm for ad7626 × In 5 mm lfcsp package, the volume is 70% smaller than that of similar products, and the power consumption is only 130 MW. Even at the highest sampling rate, the power consumption is 15% lower than that of other similar ADCs. Ad7626 adopts self synchronous LVDS bus, which provides extremely low noise interface and reduces the number of external components required to reduce circuit board level noise.

Ad7625 6-msps ADC further expands ADI's pulsar ADC product series

ADI also launched a 16 bit pulsar ADC ad7625 with a sampling rate of 6 MSPs, further expanding the number of pulsar series products to 15, with a sampling rate ranging from 1 MSPs to 10 MSPs and a dynamic range of 16 bit to 18 bit. ADI's pulsar product series is based on an ADC architecture that provides additional advantages of zero data delay, which is very important for precision data acquisition systems.
