xc6lx45 Posted July 12, 2020 Share Posted July 12, 2020 You might want to look into the implications of "full" speed USB (12 Mbps)... Link to comment Share on other sites More sharing options...
P. Fiery Posted July 13, 2020 Share Posted July 13, 2020 Pajda, I implemented isolation a few months ago and have had instant and durable operation at the highest speed the AD2 is capable of by using this device: https://hifimediy.com/product/hifime-high-speed-usb-isolator/ I haven't stressed it by using it to measure across any particularly challenging reference frame differences like a circuit referenced to a high voltage or for example the high side AC line, but it does work reliably and at high speed, (not just full speed) and does provide the ground noise isolation I need in my work. I have no connection to this company other than having bought one if these devices. Link to comment Share on other sites More sharing options...
attila Posted July 13, 2020 Share Posted July 13, 2020 Hi @pajda The full-speed isolator will reduce the capture rate, but in most of the use cases this is not important.https://forum.digilentinc.com/topic/19955-defect-power-supply-ad2/?do=findComment&comment=55427 The following client had problems with expensive high-speed isolator:https://forum.digilentinc.com/topic/19132-analog-discovery-2-analog-input-problem/?do=findComment&comment=53294 Link to comment Share on other sites More sharing options...
