USB Isolator - Mini

This USB isolator is an alternative to our other USB isolator part UISO3. This isolator is smaller and made from mainstream components which makes it a good economic alternative but still with quality components making sure a reliable isolation is achieved.

If you need to isolate your USB device from your computer this USB Isolator is an effective and easy solution to ensure total isolation between your USB devices and your computer. This USB isolator separates both the data lines and power supply from your computer, fully protecting your USB devices and data signals against electrical noise, high voltage spikes, surges and ground loops for up to 3000V, which otherwise easily could damage your equipment. USB isolation is crucial for preventing direct electrical connections between devices while maintaining their ability to function together, thereby protecting both the equipment and the data being transmitted.

Isolation is achieved by the ADUM4160 from Analog Devices, which efficiently protects your equipment against all types of high voltage spikes, surges and static electricity. The ADUM4160 makes this USB isolator compatible with both low speed (1.5M) and high speed (12M).

Power is provided from the computer’s USB port, however an external power supply can be connected to the isolator if your USB device has a high current consumption (400mA or more). Adding an external 5V power supply will ensure that the connected USB device(s) will get sufficient power. Power is isolated by a DC-DC converter with an isolation of 3000V.

Understanding USB Isolators

A USB isolator is a crucial device that provides electrical isolation between a computer and a connected USB device. By creating a barrier between the two, it prevents electrical noise, ground loops, and surges from affecting the connected device. This isolation is particularly important in applications involving sensitive equipment, such as audio converters, medical devices, or industrial control systems. By isolating the USB connection, the USB isolator ensures reliable data transfer and protects the connected device from potential damage, making it an essential tool for maintaining the integrity and performance of your USB devices.

Benefits of Using a USB Isolator

Using a USB isolator offers several significant benefits:

• Elimination of Ground Loop Problems: Ground loops can introduce electrical noise and interference, negatively impacting the performance of connected devices. A USB isolator effectively eliminates ground loops, ensuring a clean and reliable data transfer.
