The NSI3600D is a high performance isolated amplifier with integrated isolated power supply that accept fully-differential input of ±250mV. The integrated isolated power supply enables single-power operation on the low side of the device without the need for a separate isolated power supply for the high side, effectively reducing the board area. The fully differential input is ideally suited for AC or shunt current monitoring in high voltage applications where isolation is required. The device has a fixed gain of 8.2 and provides a differential analog output. The low offset and gain drift ensure the accuracy over the entire temperature range. High common-mode transient immunity ensures that the device is able to provide accurate and reliable measurements even in the presence of high-power switching such as in power supply and motor control applications. The integrated isolated power supply detection and the open-drain diagnosis output simplify system-level design and diagnostics.
