The accurate transmission of analog signals over long distances in noisy industrial environments is a difficult design problem. One of the oldest solutionsisolated current loopsis still one of the ...

Texas Instruments has added an analogue version of the non-optical replacement for digital opto-isolators it just revealed. Called ‘opto-emulators’, both analogue and digital versions replace the LED ...

In many design situations, it’s the small, single-function devices that can overcome system challenges and weak spots by eliminating subsystem-interface concerns. Such is often the case with analog- ...

There is a common misconception that optocouplers will always fail with an “open” circuit when a high-voltage event breaks the device. Although there are many ways that an optocoupler can fail open, ...
