8.4.4 High Signal Throughput

With a bandwidth of 1 MHz at a gain of 20 V/V and a slew rate of 5 V/µs, the INA296x is specifically designed for

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

less than 2 µs for a system measuring a 75-A threshold on a 2-mΩ shunt.
