Analog Devices Inc. introduced a series of voltage references specifically suited for high-resolution data converters and precision applications in data acquisition systems, instrumentation, process control, and automotive battery monitoring.
With low frequency noise of 0.5 ppm, maximum temperature coefficient of 2 ppm/°C over the full operating temperature range of -40 °C to +125 °C, and a typical long-term drift of only 25 ppm/1khr, the ADR45xx series of voltage references provide high accuracy over time and temperature variations critical for many precision applications. This performance is achieved with a maximum quiescent current of 950 µA.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
