The LTM®2882 is an isolated RS232 transceiver that guards against large ground-to-ground differentials. The LTM2882’s internal inductive isolation barrier breaks ground loops by isolating the logic level interface and line transceiver. An onboard DC/DC converter provides power to the transceiver, with an isolated 5V supply output for powering additional system circuitry. With 2500VRMS galvanic isolation, onboard secondary power and two RS232 drivers and receivers, the LTM2882 requires no external components and provides a small, complete µModule solution for isolated serial data communications.
The LTM2882 is an isolated RS232 transceiver designed to guard against large ground-to-ground differentials. It utilizes Isolator uModule Technology with coupled signal inductors embedded in the substrate to ensure consistent ruggedness and reliability, certified by UL, CSA, and IEC.
