Overview
The LTM2882IY-3 from Analog Devices Inc. is a complete galvanically isolated dual RS232 µModule (micromodule) transceiver with integrated power. This device requires no external components and is powered by a single supply, which powers both sides of the interface through an integrated, isolated DC/DC converter. It features a logic supply pin that allows easy interfacing with different logic levels from 1.62V to 5.5V, independent of the main supply. The LTM2882IY-3 is designed to provide high isolation of 2500VRMS between the line transceiver and the logic interface, making it ideal for systems with different grounds and large common mode voltages.
