Yes, USB-ISO isolates the grounds and according to some Audiophile customers of ours there is a significant improvement in their USB DAC sound after using the USB-ISO as an isolation for the ground loops between their computers and audio equipment.As my acoustic preferences have evolved with a few years in this hobby, I have come to realize that your average PC makes for a pretty lousy source component.

Can I use USB-ISO for removing the ground loops between my computer and my Audio HIFI equipment?.Note that USB-ISO can NOT work with devices that require only High Speed USB (480 Mbps) or only Low Speed USB (1.5 Mbps)! If your device is properly recognized by the personal computer without USB-ISO but unrecognized when using USB-ISO then either your device does not support Full Speed USB (12 Mbps) or your target requires more power. My device is not recognized when I connect it via USB-ISO.In such cases it would necessary to apply an external power supply too. However, some laptops and other USB host devices do not provide enough power for your USB devices.

Typically, USB-ISO works without the need of an external power supply.

Do I need to apply external power supply?.

Power jack for external power supply +8-15VDC, note the data lines are alway isolated but the power supply lines from the external power supply are not isolated from the USB_HOST connector (the personal computer is always protected the power supply and the device connected to the USB_HOST might influnce each other in case of fault).

DC-DC converter supplies isolated voltage to the USB_HOST from the USB_DEVICE if no external power supply is present.

USB_HOST connector which is USB-A type and have to be connected to the USB device like USB equipment, audio equippment, development board, programmer, debugger etc.

USB_DEVICE connector- which is USB-B type and have to be connected to the PC USB host.

High common-mode transient immunity: >25 kV/µs.

Class 3A contact ESD performance per ANSI/ESD STM5.1-2007.

Short-circuit protection for xD+ and xD- lines.

Fits USB Audio Class 1 standard (the maximum throughput is 12 Mbps and 24 bits / 96 KHz.).

Requires USB device that support USB 1.1 Full Speed mode (data rate up to 12 Mbps).

USB isolation 1000VDC between USB host and USB device.

Even if your target is not connected to a high voltage, USB-ISO gives additional protection to your valuable computer, laptop etc. This way you can connect to your PC programmers and debuggers which work directly with targets at high voltages like 220V mains power supply etc. This device is very useful as protects your PC computer USB host from overvoltages, ESD shock, and it provides a 1000VDC isolation. USB-ISO is a USB Full speed USB 2.0 compliant port isolator with a 1000V isolation voltage. USB-ISO (FULL SPEED USB ISOLATOR 1000VDC)
