ADM3251EARWZ

ADM3251E is a high speed, 2.5KV fully isolated, single-channel RS-232/V.28 transceiver device that operates from a single 5V power supply. Due to the high ESD protection on the RIN and T OUT pins, the device is ideally suited for operation in electrically harsh environments or where RS-232 cables are frequently being plugged and unplugged. The ADM3251E incorporates dual-channel digital isolators with isoPower™ integrated, isolated power. There is no requirement to use a separate isolated DC-to-DC converter. Chip-scale transformer iCoupler® technology from Analog Devices, Inc., is used both for the isolation of the logic signals as well as for the integrated DC-to-DC converter. Typical application includes high noise data communications, industrial communications, general-purpose RS232 data links, industrial/telecommunications diagnostic ports and medical equipment.
