The MAX4249–MAX4257 low-noise, low-distortion oper-ational amplifiers offer Rail-to-Rail® outputs and single-supply operation down to 2.4V. They draw only 400µA of quiescent supply current per amplifier while featuring ultra-low distortion (0.0002% THD), as well as low input voltage noise density (7.9nV/√Hz) and low input current noise density (0.5fA/√Hz). These features make the devices an ideal choice for portable/battery-powered applications that require low distortion and/or low noise.
For additional power conservation, the MAX4249/MAX4251/MAX4253/MAX4256 offer a low-power shut-down mode that reduces supply current to 0.5µA andputs the amplifiers’ outputs into a high-impedance state.The MAX4249–MAX4257’s outputs swing rail-to-rail andtheir input common-mode voltage range includesground. The MAX4250–MAX4254 are unity-gain stable;the MAX4249/MAX4255/MAX4256/MAX4257 are internal-ly compensated for gains of 10V/V or greater. The singleMAX4250/MAX4255 are available in a space-saving, 5-pin SOT23 package.
