ADM3252EABCZ

ADM3252E is a high speed, 2.5KV, fully isolated, dual channel RS-232/V.28 transceiver device that is operational from a single 3.3V or 5V power supply. Because of high ESD protection on the RIN1, RIN2, TOUT1, and TOUT2 pins, this device is ideally suited for operation in electrically harsh environments or where RS-232 cables are frequently plugged and unplugged. It provides four independent isolation channels using the integrated and isolated power of isoPower™. Chip scale transformer iCoupler® technology from Analog Devices, Inc., It is used for both the isolation of the logic signals and the integrated DC to DC converter. The result is a total isolation solution. isoPower technology in the device uses high frequency switching elements to transfer power through its transformer. It is used in application such as isolated RS-232 interface, high noise data communications, industrial communications, industrial/telecommunications diagnostic ports, medical equipment etc.
