ADUM3160 Isolation Module Digital Signal Isolation Module Audio Power Isolator USB to USB Audio Signal Isolator 12Mbps Adum3160 1500V

Works great. I use it with HF transceiver.

Absolutely waste of money in my work truck I do not have Bluetooth on my radio I only have AUX so I use a double-ended 3.5 mm headphone cord to go between the radio and phone's headphone jack but when I plug the phone into the charger of the truck whether it be the built-in USB of the truck or the cigarette lighter with USB charging adapter I get buzzing through the speakers just eliminates the buzzing however my phone doesn't charge it does not pass enough power through it to charge my phone I thought it was charging slowly way slower than normal but using this device for about 2 weeks 10 hours a day it didn't seem to be working so I plugged it into a USB to USB power meter and it was only showing maybe a quarter of an amp max output which isn't enough to keep up with the phone ... Go with the 3.5 mm noise canceling adapter it looks similar to this but it's a little smaller rounder and it hooks through the headphone port rather than USB

I have a Cox cable system feeding my TV. The cable box is grounded to the incoming coax cable. For whatever reason, the Cox ground is at a different voltage potential than my house ground, causing (loud) audio hum for any output device connected to my NUC.On the NUC, I run Roon music player. My audio path is NUC USB out to an AudioQuest Dragonfly Red, and from there directly to my power amplifiers.The only problem I had with this ground loop interrupter is that the back of the NUC is crowded, and the broad "shoulders" of this device prevented me from plugging it directly into the NUC (physical interference). My solution was to plug in another device that would fit. So my signal chain is now: AudioQuest Jitterbug (plugged directly into the NUC) + this ADUM isolater (plugged into the Jitterbug + AudioQuest Dragonfly Red (plugged into the isolator) + 1/8" analog stereo plug to dual RCA outputs (plugged into the Dragonfly).And before anyone jumps on me, yes - I've read the reports saying that the Jitterbug does nothing. In my case, I'm just using it as a spacer, so I don't care if it works or not (I bought mine used on eBay for virtually nothing).This leaves a train of devices hanging off of the delicate NUC USB outlet port. To prevent NUC damage, I've used a couple of wooden spacers to support the Dragonfly and remove stress from the NUC motherboard.So, from an electrical standpoint, the ADUM ground-plane isolator works GREAT. For the price, I recommend it highly!Boomzilla (aka Glenn Young)

This device fixed my problem! Had audio noise on a Motorola GR1225 going through a Masters Communications RA-25 USB interface. I tried everything. In-line audio noise filter, eliminating ground loops, extra grounding, etc. Nothing fixed it until I plugged this device in! Amazing! I can see where other people may have an issue with charging phones etc. That is not what it is for so don't complain that it is a bad product. It works!I wish it was cheaper but hey, if it solves a problem, I'll pay the $$$.

I'm using this to isolate a laptop from a USB Hub used for development. i.e.. Arduino, etc.The Hub works properly using low speed USB devices as expected. I didn't plan on using this to directly drive an Arduino and it wont.Test Results:Isolation verified for both GND and VCCLoad Output0mA 5.20V25mA 5.04V50mA 4.90V75mA 4.77V100mA 4.64V

Like many of us with complex MIDI studios and computer workstations, noise injected via MIDI connections can be maddening. I was getting significant high frequency noise from my Deepmind 12 when USB MIDI was connected but the noise disappeared when I unplugged the USB cable. This isolation module 100% solved that problem!Keep in mind that the Deepmind is powered by 120V and not via USB. I have *not* tried to power one of my other synths through this device and I suspect (based on other reviews) that it might not work for anything requiring more than a trickle of current. But...this should work great on any device that has the option for powering separate from USB.

I read the other reviews saying it can't pass enough current to power most devices, and thought I was fine because my USB device had external power. However, it was not recognized on my PC when inserting the isolator between the device and PC.I bought it to prevent a ground loop in my guitar processor (Boss GT-1000CORE) when connecting it to my PC via USB and also to the same power strip that the computer uses. Thought this would be a slam dunk since the processor has its own power supply.

Just a cautionary tale -This did not work for me. In fact, my usb audio interface simply does not work at all with this in place. I am still giving it 3 stars because maybe it will work for whatever you need it for, but...If you are like me and have a bad EMI/Coil Whine noise that comes out of your speakers when your computer's GPU/cpu?, but mainly GPU is working hard, be advised that my Focusrite Scarlett usb audio interface simply does not work when run through this.And I have the 8i6 model, which is not powered by the usb bus, so.... yeah, I did not get to the point where I tried to see if my speakers would be quiet while gaming. My speakers became quiet when.... well, my speakers aren't speaking any kind of sound with this standing between the cord and the PC.
