    Product Details

    The ADuM1252S evaluation kit (EV kit) is a fully assembled and tested circuit board that demonstrates the features of the ADuM1252, a 2-channel bidirectional reinforced digital isolator with ultra-low standby current in an 8-pin narrow SOIC surface-mount package. The ADuM1252S EV kit can be used to evaluate the functionality and electrical performance of the ADuM1252. The EV kit is powered by two independent power supplies.

    The ADuM1252S EV kit can also be used to evaluate the ADuM1253, ADuM1254, or ADuM1255.
