The I/O capabilities built into most microcontrollers make it easy to measure the analog world. Say you want to build a data logger for temperature. All you need to do is get some kind of sensor that ...

Open-loop current sensors have a definite price advantage over closed-loop counterparts. While you can use them in drive applications where torque accuracy isn't demanding — such as pump and fan ...

You know the “just add a transistor” drill by now: a performance or functionality requirement comes up that you can’t support entirely using the blocks built into your favorite mixed-signal ...

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 ...

Industrial temperature sensors are widely used with 4–20mA current-loop transmitters in industrial control and automation. In the current loop the temperature sensor converts a temperature into a ...
