This application note’s primary goal is to provide an easy-to-understand primer for users who are not familiar with 4-20mA current-loops and their applications. Some of the many topics discussed ...

A serial transmission method that uses a closed loop. It originated with teletype machines that transmitted 20 mA (milliamperes) of current for a 1 bit and the absence of current for a 0 bit. A 60 mA ...

Significant efficiency and performance improvements can be realized by improving the current loop’s power supplies, replacing linear regulators with high-efficiency buck regulators. It also increases ...

Popularity and perceived advantages of current-mode control (CMC) have made it de rigueur as a loop control architecture with many power management IC manufacturers and power supply vendors. Also ...

IoT connectivity is a hot topic, but it’s not a new idea, except for the “Internet” aspect. Industrial and some commercial applications have been connecting all sorts of sensors and transducers to ...

Here’s a question for you: when your PCB has a ground plane layer, where do return signals flow? It seems like a trick question, but as [Kristof Mulier] explains, there’s more to return path routing ...

A satellite map of the Gulf of Mexico reveals the “loop current,” a hairpin curve of hotter than usual water that could help grow future Hurricane Helene into a Category 3 storm. University of Miami ...

TAMPA, Fla. (WFLA) — The Gulf Loop Current is a large pool of hot water a couple hundred miles west of Tampa Bay. This hurricane season, it’s looking even more imposing than normal. The loop current ...
