Demonstration circuit 1794A is an isolated RS485/RS422 μModule® transceiver + power featuring the LTM2885. The demo circuit is a 6500VRMS galvanically isolated RS485/ RS422 transceiver interface. The demo circuit features an EMI optimized circuit configuration and printed circuit board layout. 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.
