Linear Technology has developed a line of µModule isolators that simplifies the design of isolated systems by simply plugging in a module, without the need for complex barrier components. µModule isolators use magnetically coupled techniques to provide data and power isolation in a single package, without the need for external components. The LTM2881 isolated RS485/RS422 transceiver and LTM2882 dual isolated RS232 transceivers use µModule isolator technology to provide complete transceiver-plus-power solutions in 15mm × 11.25mm × 2.8mm surface mount packages.

The document describes the operation of inductively coupled coils for data transmission, which supports a minimum throughput rate of approximately 21 Mbps. It also covers isolated power transmission using a full-bridge square wave oscillator and low-dropout linear regulator, offering input voltage ranges from 3V to 5.5V.
