ADM2483BRWZ Description
The ADM2483BRWZ differential bus transceiver is an integrated, galvanically isolated component designed for bidirectional data
communication on balanced, multipoint bus transmission lines. It complies with ANSI EIA/TIA-485-A and ISO 8482: 1987(E).
Using the iCoupler technology from Analog Devices, Inc., the ADM2483 combines a 3-channel isolator, a three-state differential
line driver, and a differential input receiver into a single package. The logic side of the device is powered with either a 5 V or 3 V
supply, and the bus side uses a 5 V supply only.
