Product Details

The EVAL-ADuM3471EBZ demonstrates two separate applications for the ADuM347x family of quad-channel digital isolators with integrated transformer drivers. It has two independent power supply circuits: a double supply and a single supply. The switching frequency can be set from 200 kHz to 1000 kHz. The board supports a variety of I/O configurations and multiple transformer options. It is equipped with two ADuM3471 isolators.
