App note: Difference amplifier vs. current-sense amplifier for high side current measurement

in app notes by DP | 0 comments

Here’s an article from Analog Devices detailing the differences between current-sense amplifiers and difference amplifiers in high side current measurement. Current sense amplifiers offer measurement of the instantaneous current, while difference amplifiers offer average current measurements.  While current-sense amplifiers offer … Read more

App note: Layered isolation with high power digital isolators

in app notes by DP | 7 comments

Sequentially connecting optocouplers for better isolation slows things way down, digital isolators don’t suffer as much. The advantages of digital isolators over opto-couplers [PDF!] in layered isolation: Creating double insulation barriers with sequential optocouplers is problematic because the data integrity … Read more
