Working Principles

The ADM3488ARZ is designed to facilitate reliable data communication over long distances using the RS-485/RS-422 standard. It employs differential signaling, where data is transmitted as the voltage difference between two lines (A and B). This method provides noise immunity and allows for longer cable lengths.

The driver section of the IC converts the logic-level signals into differential voltages, while the receiver section converts the received differential voltages back into logic-level signals. The DE/RE pin controls the direction of data flow by enabling either the driver or receiver.
