Output 15 V
IC revisionA

Description

Demonstration circuit 1794A is an isolated RS485/RS422μModule® transceiver + power featuring the LTM®2885. Thedemo circuit is a 6500VRMS galvanically isolated RS485/RS422 transceiver interface. The demo circuit featuresan EMI optimized circuit configuration and printed circuitboard layout. The demo circuit operates from a singleexternal supply on VCC. The part generates the output voltage VCC2 and communicates all necessary signalingacross the isolation barrier using LTC’s isolator μModuletechnology.
