Static common-mode specifications have been the traditional standard used to measure isolators and compare devices with different construction or technologies. However, that standard is no longer an ...

This article is part of the Ideas for Design Series: Vol. 3, No. 8. This circuit builds on a previous idea in which the addition of an optocoupler to a microcontroller output converted a “dumb” ...
