ADM3251E:  隔离式单通道RS-232线路驱动器/接收机

产品详情

ADM3251E是一款高速、2.5 kV完全隔离、单通道RS-232/V.28收发器,采用5 V单电源供电。由于 RIN 和TOUT 引脚提供高压ESD保护,因此该器件非常适合在恶劣的电气环境中工作,或频繁插拔RS-232电缆的场合。

无需使用单独的隔离DC-DC转换器。ADI公司的芯片级变压器iCoupler® 技术,能够同时用于隔离逻辑信号和集成式DC-DC转换器,因此该器件可提供整体隔离解决方案。

ADM3251E符合EIA-232E规范,并且数据速率高达460 kbps。

倍压器/反相器使用四个外部0.1 μF电荷泵电容,这使得该器件可以采用5 V单电源供电。

ADM3251E提供20引脚、宽体SOIC封装,额定温度范围为−40°C至+85°C。

应用
--高噪声数据通信
--工业通信
--通用RS-232数据链路
--工业/电信诊断端口
--医疗设备

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.
