RS-232 transceiver has isolated power

The LTM2882 dual-channel isolated RS-232 transceiver µModule breaks ground loops by isolating the logic interface and line transceiver using internal inductive signal and power isolation, allowing for a much larger common-mode voltage range.

The module comes in low-profile 11.25 x 15 x 2.8-mm LGA and BGA packages. It has 2,500 VRMS isolation, and its ±10-kV ESD-protected transceiver operates at up to 1 Mbits/s and takes only 30 µA when disabled. The two drivers can be enabled and disabled in less than 2 µs and are protected from short circuits. (From $8.45 ea/1,000 — available now.)
