Analog Devices ADuM4160 | Demoboard EVAL-ADuM4160EBZ

Beschreibung

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 iCoupler® USB isolators to address the difficult task of isolating the bus. The EVAL-ADuM4160EBZ USB isolator evaluation board allows for an easy interface to existing applications by standard cabling or discrete wiring. This USB evaluation board comes populated with an ADuM4160; however, because the ADuM4160 and ADuM3160 are electrically identical and pin compatible, any evaluation done with this board and component also applies directly to the ADuM3160. If the user wants to substitute the ADuM3160 on the printed circuit board (PCB), no other changes are required.
