ADM3251E:  隔离的单通道RS-232线驱动器/接收器

ADM3251E是一款高速、单通道RS-232收发器，采用单电源供电。这款器件非常适于工作在苛刻的电气环境，或频繁插拔RS-232电缆的环境中。

ADM3251E集成了双通道数字隔离器以及isoPower集成隔离电源。由于内置ADI公司iCoupler®技术的芯片级DC-DC转换器，因此无需外部分立的隔离DC-DC转换器。

ADI公司的芯片级变压器iCoupler技术不仅可用与隔离逻辑信号，还可以用于DC-DC转换器的隔离，在小封装内提供了完整的隔离解决方案。

在单电源工作时，电压倍压器/逆变器需要使用五个外部0.1µF电荷泵电容。

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