DC/DC Supply Sources and Sinks Current from 5 to 24V Input

Victor Khasiev, Analog Devices

Most electronic systems depend on power voltage rails that are either positive or negative, but a few applications require individual rails that can be both. In these situations, positive or negative power is supplied by the same terminal—that is, the output voltage of the supply can be adjusted through its en

How to Choose the Optimal Smart Handheld Gage

George Schuetz, Mahr Inc.

In manufacturing, it makes perfect sense to maximize the value of every dollar, but it also means hard choices must be made when selecting handheld gages. For example, myriad issues such as training, warranties, throughput requirements, manufacturing methods and materials, the end-use of the workpiece, and general co
