Product Description

ADM2582E/ADM2587E是具备±15 kV ESD保护功能的完全集成式隔离数据收发器，适合用于多点传输线路上的高速通信应用。ADM2582E/ADM2587E包含一个集成式隔离DC/DC电源，不再需要外部DC/DC隔离模块。

该器件针对均衡的传输线路而设计，符合ANSI/TIA/EIA RS-485-A-98和ISO 8482:1987(E)标准。它采用ADI公司的iCoupler®技术，在单个封装内集成了一个三通道隔离器、一个三态差分线路驱动器、一个差分输入接收机和一个isoPowerTM DC/DC转换器。该器件采用5V或3.3V单电源供电，从而实现了完全隔离的RS-485解决方案。

ADM2582E/ADM2587E驱动器带有一个高电平有效使能电路，并且还提供一个高电平接收机有效禁用电路，可使接收机输出进入高阻抗状态。该器件具备限流和过热关断特性，能够防止输出短路，并防止出现由于总线争用而引起功耗过大的情况。它采用20引脚宽体SOIC封装，其额定工作温度范围为工业温度范围。

ADM2582E/ADM2587E集成了isoPower技术，该技术采用高频开关元件通过其变压器传输电力。在印制电路板（PCB）布局时必须特别注意满足辐射标准。欲了解电路板布局注意事项，请参考应用笔记AN-0971。
