Product Details

The EVAL-ADuM4165EBZ and the EVAL-ADuM4166EBZ allow quick and easy evaluation of the ADuM4165 and ADuM4166 USB isolators, allowing direct connection to USB hosts and peripherals without the need for additional components. The ADuM4165/ADuM4166 employ Analog Devices, Inc., iCoupler® technology to combine isolator channels, USB transceivers, power and timing circuits, control logic and internal terminations, pull-ups, and pull-downs into a single, 20-lead, wide-body, increased creepage SOIC_IC package.

The evaluation boards have a separate ground and power plane for each side of the isolator. This separation enables the evaluation of the ADuM4165/ADuM4166 with galvanic isolation between both sides of these devices. However, the boards have not been certified for safety when using high voltages, and testing must be carried out by qualified personnel only.

Power can be provided on the upstream side from a connected USB host, while an external power supply is required for the downstream side.

For full details on the ADuM4165/ADuM4166, see the ADuM4165/ADuM4166 data sheet, which must be consulted in conjunction with this user guide when using the EVAL-ADuM4165EBZ or the EVAL-ADuM4166EBZ.
