DESCRIPTION
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 confi guration 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.
