  • ADUM4190- 5kV rms 隔离误差放大器
    ADUM4190:5kV rms 隔离误差放大器

    ADuM4190是一款基于ADI公司iCoupler®技术的隔离误差放大器。ADuM4190非常适合带原边控制器的线性反馈电源，与常用的光耦合器和分流调节器解决方案相比，在瞬态响应、功率密度和稳定性方面均有所提高。

    与在整个寿命周期中和高温下具有不确定电流传输比的基于光耦合器的解决方案不同，ADuM4190的传输功能不随寿命周期而改变，在宽温度范围-40°C至125°C内保持稳定。

    它内置宽频运算放大器，可用于设置各种常用的电源环路补偿技术。ADuM4190速度足够快，允许反馈环路对快速瞬变调节和过流条件作出反应。该器件还内置一个高精度1.225V基准电压源，可与电源输出设定点进行比较。

    ADuM4190采用宽体SO-16封装，具有增强型5kVrms隔离额定值。
