6.4.2 High Signal Throughput

With a bandwidth of 1.1MHz at a gain of 20V/V and a slew rate of 2V/µs, the INA950-SEP is specifically designed for detecting and protecting applications from fast inrush currents. As shown in Table 6-2, the INA950-SEP responds in less than 2µs for a system measuring a 75A threshold on a 2mΩ shunt.
