Touchstone Semiconductor has unveiled its first Analog Devices alternate source two-channel, 12-bit, 125-ksps analog-to-digital converter that can be used as a drop-in replacement for the Analog Devices AD7887.
The Touchstone part is $3 less expensive, priced at $1.25 in 1,000-piece quantities, is pin-compatible, functionally identical and is one a total of 17 parts from Maxim and Analog Devices in its alternate-source analog IC family.
The TSA7887 is aimed as a 12-bit ADC in low-power, industrial, process control and data-acquisition applications. It is available in 8-pin SOIC and MSOP packages and is specified from -40ºC to +125ºC.
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.
