ADM2483: Slew-Rate Limited Isolated RS-485 Transceiver
Product Description
The ADM2483 differential bus transceiver is an integrated, galvanically isolated component designed for bi-directional data communication on multi-point bus transmission lines. It is designed for balanced transmission lines and complies with ANSI TIA/EIA RS-485-A and ISO 8482:1987(E). The ADM2483 employs Analog Devices’ iCoupler technology to combine a 3-channel isolator, a 3-state differential line driver and a differential input receiver into a single package. The logic side of the device can be powered with either a 5 V or a 3 V supply while the bus-side is powered with a 5 V supply.
