Linear Technology Corp has introduced the LTC2632 and LTC2633 families of dual 12-bit, 10-bit and 8-bit rail-to-rail, voltage output digital-to-analog converters (DACs), with serial SPI (LTC2632) and I2C (LTC2633) interfaces.
The LTC2632 and LTC2633 dual DACs with internal references offer accurate DC performance with a 12-bit INL of ±1LSB (max); ±5mV (max) offset error; and ±0.8 % FSR (max) gain error. AC performance includes fast 4.4µs settling time and low 2.8nV•s glitch impulse. Each dual DAC integrates a precision 10ppm/°C reference into a tiny 8-lead 3mm x 3mm TSOT-23 package. The devices are aimed at industrial, automotive, portable communications and ATE applications.

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.
