PRODUCTION DATA
With a bandwidth of 1.1 MHz at a gain of 20 V/V and a slew rate of 2 V/µs, the INAx290 is specifically designed for detecting and protecting applications from fast inrush currents. As shown in Table 7-2, the INAx290 responds in less than 2 µs for a system measuring a 75-A threshold on a 2-mΩ shunt.
