DC1503A-B

DC1503A-B is a demo board for the LTM2881 complete isolated RS485/RS422 µModule transceiver plus power. Demonstration circuit DC1503A is an Isolated RS485/RS422 μModule® transceiver + power featuring the LTM®2881. The demo circuit is a 2500VRMS galvanically isolated RS485/RS422 transceiver interface. All components are integrated into the μModule transceiver. The demo circuit operates from a supply on VCC and a logic supply on VL. The part generates the output voltage VCC2 and communicates all necessary signaling across the isolation barrier using isolation μModule technology.
