  • Product Details:

    ADuM4190是一款基于ADI公司iCoupler®技术的隔离误差放大器。ADuM4190非常适合用于线性反馈电源。ADuM4190的原边控制器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。

    Unlike optocoupler-based solutions with uncertain current transfer ratios throughout the life cycle and at high temperatures, the ADuM4190's transmission capabilities do not change with the life cycle and remain stable over a wide temperature range of -40°C to +125°C.

    The ADuM4190 has a built-in wideband op-amp that can be used in a variety of popular power loop compensation technologies. The ADuM4190 is fast enough to allow the feedback loop to react to fast transient and overcurrent conditions. The device also has a built-in high-precision 1.225 V reference that can be compared to the supply output setpoint.

    The ADuM4190 is available in a wide-body 16-pin SOIC package with a 5 kV rms rated for enhanced isolation.
