Analog Devices, Inc., the global leader in data-conversion technology, introduced today 18 power-efficient analog-to-digital converters (ADC) with resolutions ranging from 10 to 16 bits. Designed for power-sensitive communications, industrial, portable-electronics and instrumentation equipment, ADI’s new ADCs reduce power consumption by as much as 60 percent compared to many competing ADCs, while maintaining best-in-class noise performance and dynamic range.
Improved power efficiency enables wireless basestations to operate more cost effectively with better system reliability. Portable medical devices benefit from longer battery life and smaller form factors. Advanced imaging picture resolution is enhanced by increasing data-conversion channel density without adding to the power budget.
“There is a growing trend to reduce total system power with each generation, and in the past, the system designer was left with making power-versus-performance tradeoffs, especially with high speed converters,” said Jon Hall, strategic marketing and applications manager, High Speed Signal Processing, Analog Devices. “Power efficiency is a requirement across a broad range of applications, and so is hitting the target system performance. ADI’s 18 newest ADCs provide low power without sacrificing the high degree of performance the industry has come to expect from ADI.”
The flagship converter in this series, the AD9268, is the industry’s first 125-MSPS (megasamples per second) 16-bit, dual-channel ADC and consumes 376 mW per channel – 60 percent less power per channel than competing devices.
The new ADC’s integration and energy savings allow system engineers to increase channel counts without increasing a product’s board area or power consumption, enabling higher call volume in cellular base stations, for example, or improved image resolution in medical magnetic-resonance imaging (MRI) equipment. In handheld and other power-sensitive applications, ADI’s low-power ADCs likewise enable improved system performance while extending battery life in hand-held devices, such as portable spectrum analyzers.
