6.3.1 Amplifier Input Common-Mode Signal

The INA281-Q1 supports large input common-mode voltages from –4 V to +110 V. Because of the internal topology, the common-mode range is not restricted by the power-supply voltage (VS). This allows for the INA281-Q1 to be used for both low- and high-side current-sensing applications.
