... MAX4282/MAX4284); single/dual fixed gain (MAX4174/ MAX4274); and single/dual fixed gain plus internal bias at the noninverting input (MAX4175/ CC MAX4275), which simplifies input biasing in single-supply designs. The input common-mode voltage range of the open-loop amplifiers extends from 150mV below the negative supply to within 1.2V of the positive supply. The outputs can swing rail-to-rail and drive a 1k Ω ...

... 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) ...

... Single-supply systems benefit from a midsupply bias on the noninverting input (provided internally on MAX4175/MAX4275), as this produces a quiescent DC level at the center of the rail-to-rail output stage signal swing. For dual-supply systems, ground-referenced signals may be DC-coupled into the inverting or non- inverting inputs ...
