8.4.4 High Signal Throughput

With a bandwidth of 1.1 MHz at a gain of 20 V/V and a slew rate of 8 V/µs, the INA296x-Q1 is specifically

designed for detecting and protecting applications from fast inrush currents. As shown in Table 8-1, the INA296x-

Q1 responds in less than 1 µs for a system measuring a 75 A threshold on a 2 mΩ shunt.
