High Reliability Reinforced Isolated Amplifier
NSI1200-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 ±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 of 8 and provides a differential analog output.
