ADM2482E:  信号隔离RS-485收发器,全/半双工,内置变压器驱动器

产品详情

ADM2482E/ADM2487E均为隔离数据收发器,提供±15 kV ESD保护,适用于多点传输线路的高速、半双工或全双工通信。在半双工模式下,发射器输出与接收器输入共用同一传输线路。发射器输出引脚Y和Z分别在外部与接收器输入引脚A和B相连。这些器件针对平衡传输线路而设计,符合TIA/EIA-485-A-98和ISO 8482:1987(E)标准。上述器件采用ADI公司的iCoupler® 技术,将3通道隔离器、三态差分线路驱动器和差分输入接收器集成于单封装中。片内振荡器输出一对方波,以驱动外部变压器提供隔离电源。器件逻辑端可以采用5 V或3.3 V电源供电,总线端则采用3.3 V隔离电源供电。

ADM2482E/ADM2487E的驱动器具有高电平有效使能特性,接收器则具有低电平有效使能特性。当驱动器使能信号为低电平时,驱动器输出进入高阻抗状态。当接收器使能信号为高电平时,接收器输出进入高阻抗状态。

该器件具有限流和热关断特性,可防止发生输出短路以及总线竞争导致功耗过大的情况。该器件的额定温度范围为−40°C至+85°C工业温度范围,提供16引脚、宽体SOIC封装。

    Solving Isolation Challenges in Power Conversion Applications
    This webcast will present solutions to isolation challenges in power conversion applications. Among the topics to be discussed are the limitations of traditional methods of isolation (such as utilization of optocouplers and pulse transformers) vs. more efficient and cost effective solutions that utilize digital isolators. If you are currently using optocouplers and pulse transformers, this is a webcast you should attend.

    Solving Isolation Challenges in Industrial Automation
    This webcast will discuss the role isolation plays in providing protection and reducing the system bit-error-rate, using the specific design challenges of an RS-485 network. Topics to be covered in this presentation will include: Why and when one should isolate, Types of isolation and their advantages, Design Considerations for an RS-485 node (and how this translates to design considerations for signal isolation) as well as many other topics.
