National Semiconductor Corp.'s two
configurable sensor analog front-end (AFE) integrated circuits (ICs) work together with new
tools to fast-track signal path designs for a variety of sensors from major
global manufacturers. The first in a family of products, National's two
configurable sensor AFE products are each customized to a specific sensor
application and have a variety of features, including programmable current
sources, voltage reference options and adjustable sample rates. The LMP91000 is a fully configurable, low-power potentiostat that
provides a complete, integrated signal path solution between a sensor and
analog-to-digital converter (ADC). The LMP90100 is a multi-channel, low power, 24-bit sensor AFE with
true continuous background calibration and diagnostics for high performance
transmitter and transducer applications.
The configurable sensor AFE ICs and WEBENCH
Sensor AFE Designer enable the design
engineer to select a sensor, design and configure the solution and download
configuration data to the sensor AFE. A typical sensing application that today
may require several boards and up to 25 components is reduced to just one of
National's ICs and sensor system design is reduced.
The Industrial Internet of Things may be going off the deep end in connecting everything on the plant floor. Some machines, bearings, or conveyors simply donít need to be monitored -- even if they can be.
Wind turbines already are imposing structures that stretch high into the sky, but an engineering graduate student at the University of Notre Dame wants to make them even taller to reduce energy costs and improve efficiency.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies.
You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived.
