8.3.1 Amplifier Input Common-Mode Signal

The INA296x supports large input common-mode voltages from –5 V to +110 V. The internal topology of the INA296x allows the common-mode range to exceed the power-supply voltage (VS). This allows for the INA296x to be used for low-side, inline, and high-side current-sensing applications that extend beyond the supply range of 2.7 V to 20 V.
