Amplifier Input Common-Mode Range

The INA280-Q1 supports large input common-mode voltages from 2.7 V to 120 V and features a high DC CMRR of 140 dB (typical) and a 85-dB AC CMRR at 50 kHz. The minimum common-mode voltage is restricted by the supply voltage as shown in Figure 7-1. The topology of the internal amplifiers INA280-Q1 restricts operation to high-side, current-sensing applications.
