The ADM3251E1 is a high speed, 2.5 kV fully isolated, singlechannel RS-232/V.28 transceiver device that operates from a
single 5 V power supply. Due to the high ESD protection on the
RIN and TOUT 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. The result is a total isolation solution.
The ADM3251E contains isoPower technology that uses high
frequency switching elements to transfer power through the
