ANALOG DEVICES  EVAL-ADM2483EBZ  评估模块, RS 485收发器, 电气数据隔离

GENERAL DESCRIPTION

The ADM2483differential 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: 1987E. 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.
