Description

  • Universal Serial Bus (USB) Hub Isolator Circuit is rapidly becoming the standard interface for most PC peripherals. It is displacing RS-232 and the parallel printer port because of superior speed, flexibility and support of device Hot-Swap. There has been a strong desire on the part of industrial and medical equipment manufacturers to use the bus as well, but adoption has been slow because there has not been a good way to provide the isolation required for connections to machines that control dangerous voltages or low leakage defibrillation proof connections in medical applications. The ADuM4160 is designed primarily as an isolation element for a peripheral USB device
