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 ...

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 ...

Traditionally, isolated power supplies use an opto-coupler in the feedback loop to transfer regulation information across the isolation barrier. Unfortunately, an opto-coupler’s gain characteristic ...

Silicon Labs introduced the industry's first digital CMOS-based drop-in replacement solution for optocoupler-isolated gate drivers (opto-drivers). Supporting up to 5 kV isolation ratings and up to 10 ...

Once more opto-isolators are to be seen in Wonderland. The aim was to see if the faster photodiode types can operate quickly in common collector mode. They consist of an infra-red led and a fast npn ...
