ADuM3190是采用ADI公司
iCoupler®技术的隔离误差放大器。ADuM3190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。
Unlike optocoupler-based solutions with an indeterminate current transfer ratio throughout the lifecycle and at high temperatures, the ADuM3190's transmission capabilities do not change with the lifecycle and remain stable over a wide temperature range of -40°C to 125°C.
It has a built-in wideband op-amp that can be used to set up a variety of commonly used power loop compensation techniques. The ADuM3190 is fast enough to allow the feedback loop to react to fast transient regulation and overcurrent conditions. The device also has a built-in high-precision 1.225V reference that can be compared to the supply output setpoint.
The ADuM3190 is available in a small QSOP-16 package (2.5kVrms).
