App note: Complex power supply sequencing made easy

in app notes by DP | 1 comment

Power sequencing from Analog Devices using their ADP5131 sequencer IC. App note here (PDF) Power supply sequencing is required for microcontrollers, field programmable gate arrays (FPGAs), digital signal processors(DSPs), analog-to-digital converters (ADCs), and other devices that operate from multiple voltage … Read more

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
