NSi1300-Q1 High Reliability Reinforced Isolated Amplifier Datasheet (EN) 1.1
■NSI1300-Q1 is a high-performance isolated amplifier with output separated from input based on the NOVOSENSE capacitive isolation technology. The device has a linear differential input signal range of ±50mV (±64mV full-scale) or ±250mV (±320mV full-scale). The differential input is ideally suited to shunt resistor-based current sensing in high voltage applications where isolation is required.
■The device has a fixed gain (8.2 or 41) 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 fail-safe functions including input common-mode overvoltage detection and missing VDD1 detection simplify system-level design and diagnostics.
