ANALOG DEVICES LTM2882CV-5#PBF RS422/RS485 Transceiver, 1Mbps, Half Duplex, 4.5V to 5.5V Supply, LGA-32

LTM2882CV-5#PBF is a complete galvanically isolated dual RS232 µModule® (micromodule)transceiver + power. No external components are required. A single 3.3V or 5V supply powers both sides of the interface through an integrated, isolated DC/DC converter. A logic supply pin allows easy interfacing with different logic levels from 1.62V to 5.5V, independent of the main supply. Coupled inductors and an isolation power transformer provide 2500VRMS of isolation between line transceiver and the logic interface. This device is ideal for systems with different grounds, allowing for large common mode voltages. Uninterrupted communication is guaranteed for common mode transients greater than 30kV/?s. Applications include isolated RS232 interface, industrial communication, test and measurement equipment, and breaking RS232 ground loops.

• Input voltage range from 4.5V to 5.5V, no external components required
• RS232 transceiver: 2500VRMS for 1 minute, 1µA max input supply current at (ON = 0V)
