8.4.1 Normal Mode
The INAx181-Q1 are in normal operation when the following conditions are met:
- The power supply voltage (VS) is between 2.7 V and 5.5 V.
- The common-mode voltage (VCM) is within the specified range of –0.2 V to +26 V.
- The maximum differential input signal times gain plus VREF is less than VS minus the output voltage swing to VS.
- The minimum differential input signal times gain plus VREF is greater than the swing to GND (see the Rail-to-Rail Output Swing section).
During normal operation, these devices produce an output voltage that is the gained-up representation of the difference voltage from IN+ to IN– plus the reference voltage at VREF.
