... Three versions are available in this amplifier family: single/ dual/quad open-loop, unity-gain stable (MAX4281/ 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 ...

... Capacitive Load Stability C LOAD Power-Up Time Note 1: MAX4174/MAX4175/MAX4281 and MAX4274/MAX4275/MAX4282 and MAX4284 are 100% production tested +25°C. All temperature limits are guaranteed by design. A Note 2: Guaranteed by design. Note 3: The input common-mode range for IN_+ is guaranteed by a functional test. A similar test is done on the IN_- input. See the Applications Information section for more information on the input voltage range of the GainAmp ...

... 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) ...
