The ISO1228EVM is an evaluation module (EVM) used to evaluate the 8-channel isolated digital input receiver ISO1228 in the 38-pin DFB SSOP package. The EVM can be used to evaluate sink, source, and sink/source mode operation with no change to the PCB circuitry. The board also has additional footprints that gives the user flexibility to add components to test a variety of common applications. The EVM features multiple test points and jumper options to evaluate the device with minimal external components.
