Product Summary
The ADM2483BRW is a differential bus transceiver. The ADM2483BRW is an integrated, galvanically isolated component designed for bidirectional data communication on balanced, multipoint bus transmission lines. The ADM2483BRW complies with ANSI EIA/TIA-485-A and ISO 8482: 1987(E). Using Analog Devices iCoupler technology, 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.
