In the previous two issues of this newsletter, we looked at troubleshooting digital input modules. Basically, we looked for the presence or absence of a voltage. With analog modules, it's trickier ...

The Solves-It! analog plug-in programmable logic controllers (PLC) are targeted for small-system control and monitoring where speed, pressure, or other analog processes are involved. Just like its ...

Editor’s note: Here is an article regarding a new approach to analog isolation. Each application example makes use of a high-current PVI as an isolated power source, a micropower digital isolator, and ...

Many of today's applications require current measurement for power estimation, regulation purposes, or for diagnostics. This article focuses on circuits with analog outputs that are needed for loop ...

How to decide between buffered and un-buffered (switched capacitor), high-speed analog-to-digital converters, with an example of anti-aliasing filter design. The fundamental end goal when using an ADC ...
