Ieper, Belgium Melexis introduces a versatile, fully integrated and programmable sensor interface solution for automotive and industrial applications. The MLX90320 provides amplification, calibration and temperature compensation for virtually all kinds of resistive bridge type sensors including pressure transducers, strain gauges and position sensors. The MLX90320 can help design engineers to optimize their application in terms of cost, space and time to market. With very few additional components the circuit will amplify an analogue ratiometric input signal to achieve the desired output signal. This output signal can be corrected for sensitivity and offset errors due to temperature effects. The ASIC calibrates the sensor output by nulling the offset voltage and by applying the appropriate signal gain to calibrate the output voltage span between 0V and 5V. Error calibration is accomplished via various DACs. The digital coefficients, which determine the calibration parameters, are stored in an on-chip EEPROM. Both gain and offset have coarse and fine DACs, allowing a very accurate calibration over a wide range of input errors. Melexis NV , Ieper, Belgium. www.melexis.com.
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.
