DC1746A-B

DC1746A-B is a demo board for LTM2881 complete Isolated RS485/RS422 µModule transceiver + power. Demonstration circuit 1746A is an isolated RS485/RS422 μModule® transceiver + power featuring the LTM®2881. The demo circuit is a 2500VRMS galvanically isolated RS485/RS422 transceiver interface. The demo circuit features an EMI optimized circuit configuration and printed circuit board layout. All components are integrated into the μModule transceiver. The demo circuit operates from a single external supply on VCC. The part generates the output voltage VCC2 and communicates all necessary signaling across the isolation barrier using LTC’s isolator μModule technology.
