Analog Devices Inc. ADM3095E RS-485收发器

Analog Devices ADM3095E收发器是完全集成的电磁兼容性(EMC)保护RS-485收发器。该设计将过压故障保护、浪涌保护、EFT保护、ESD保护和扩展共模输入电压范围相结合。这些3V至5.5V、2.5Mbps、RS-485收发器的RS-485总线引脚上可提供高达±42V的交流/直流峰值总线过压故障保护功能。 此外，这些收发器的总线引脚还可提供高达±2kV的IEC 61000-4-4 4级EFT保护和IEC 61000-4-2 4级ESD保护。得益于这些保护特性，ADM3095E器件的接口引脚可承受高达±15 kV的电压，而不会发生闩锁或损坏。ADM3095E RS-485收发器具有±25V的扩展共模输入电压范围。借助扩展共模输入电压范围，ADM3095E能够在具有接地环路电压、电缆较长的嘈杂环境中提高数据通信的可靠性。ADM3095E RS-485收发器非常适合用于HVAC网络、工业现场总线、楼宇自动化和公用事业网络等应用。
