7.3.1 Amplifier Input Common-Mode Range

The INAx290 supports large input common-mode voltages from 2.7 V to 120 V and features a high DC CMRR of 160 dB (typical) and a 85-dB AC CMRR at 50 kHz. The minimum common-mode voltage as shown in Figure 7-1 is restricted by the supply voltage. The topology of the internal amplifiers INAx290 restricts operation to high-side, current-sensing applications.
