Medical and Industrial Application USB to USB Isolator up to Full Speed 12Mbps
USB Isolator protects your PC or Laptop while connecting USB peripherals which is wired to high voltages. This small, industrial - grade isolator is very easy for use and provides a high-voltage barrier for protection against surges, noise and ground loop errors. It is suitable for use in sensitive applications like automotive measurements.
USB isolator provides a high - voltage isolation barrier between computer and its connected USB device. The isolation protects equipment from electrical over-voltages and transient voltage spikes. By eliminates ground loop currents flowing between the PC and USB device which can cause damage and inaccurate measurements. Additionally, isolation minimizes conducted noise from static discharge, magnetic fields and radio frequency interference.
USB isolator is USB bus powered and can provide 5V 320mA to your USB device with built-in isolated DC to DC converter. This is possible when the isolator is connected to a high power USB host port.

A note about the chip:
USB use has displaced older communications standards, such as RS-232, as the default serial communications port in PC-based systems. When compared to these other standards, USB has many enhanced features, such as power for peripherals, automatic driver installation, and higher data rates. However, when using USB, it is difficult to provide isolation, which has limited its acceptance in medical and industrial applications.
Analog Devices, Inc., has introduced the ADuM4160 and ADuM3160 USB isolators to address the difficult task of isolating the bus.
