... G care must be taken not to saturate the inputs/output of the core op amp, to avoid signal distortions or clipping. The inverting inputs (IN_-) of the MAX4174/MAX4175/ MAX4274/MAX4275 must be within the supply rails or signal distortion may result. The GainAmp’s inverting input structure includes diodes to both supplies, such that driving the inverting input beyond the rails may cause signal distortions (Figure 1) ...
