The NSI3612D is a high performance isolated amplifier with integrated isolated power supply that accept fully-differential input of ±1V. 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 high input impedance of NSI3612D makes it highly suitable for connection to high-voltage resistive dividers or other voltage signal sources with high output resistance. The device has a fixed gain of 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 motor control applications. The integrated isolated power supply detection and the open-drain diagnosis output simplify system-level design and diagnostics.
