Isolated RS485 Transceiver with Power in One Small Package - LTM2881

Jeff Marvin - Design Center Manager Nov 15th 2009

The benefits of galvanic isolation extend beyond safety and protection from dangerous voltages to provide error-free communication in the presence of high edge rate transients, noise and high common mode voltage that would otherwise render a non-isolated network inoperative. The new Isolator uModule Technology from Linear Technology provides a complete power and data isolation solution in one small 11.25mm x 15mm x 2.8mm surfacemount package. The LTM2881 incorporates a robust isolated RS485 transceiver and an isolated DC/DC converter capable of delivering up to 1W of power for the transceiver and auxiliary circuits. The module requires no external components – even the decoupling capacitors and an electrically switchable network termination resistor are built in. The ease of use and a small footprint make it more appealing than ever to design isolation into an RS485 network at every communication node.
