The input common-mode voltage range The MAX4249–MAX4257 single-supply operational extends from V amplifiers feature ultra-low noise and distortion while DD - 1.1V to 200mV beyond the negative rail. The push-pull output stage maintains excellent DC consuming very little power. Their low distortion and low characteristics, while delivering up to ±5mA of current. noise make them ideal for use as preamplifiers in wide dynamic-range applications, such as 16-bit analog-to- The MAX4250–4254 are unity-gain stable, whereas, the digital converters (see Typical Operating Circuit). Their MAX4249/MAX4255/MAX4256/MAX4257 have a higher high-input impedance and low noise are also useful for slew rate and are stable for gains # 10V/V. The signal conditioning of high-impedance sources, such MAX4249/MAX4251/MAX4253/MAX4256 feature a low- as piezoelectric transducers. power shutdown mode, which reduces the supply cur- rent to 0.5µA and disables the outputs. These devices have true rail-to-rail output operation, drive loads as low as 1k" while maintaining DC accura- The MAX4250AAUK is specified for operation over the automotive (-40°C to +125°C) temperature range.
