The ADM3252EABCZ is a high-speed isolated 2-channel Line Driver/Receiver operational from a single 3.3 or 5V power supply. Because of high ESD protection on the RIN1, RIN2, TOUT1 and TOUT2 pins, the ADM3252E is ideally suited for operation in electrically harsh environments or where RS-232 cables are frequently plugged and unplugged. The ADM3252E provides four independent isolation channels using the integrated and isolated power of isoPower™. There is no requirement to use a separate isolated DC-to-DC converter. Chip scale transformer iCoupler® technology from Analog Devices Inc., 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 ADM3252E uses high frequency switching elements to transfer power through its transformer. Special care must be taken during printed circuit board (PCB) layout to meet emissions standards.
