♦ Low Input Voltage Noise Density: 7.9nV/√Hz

♦ Low Input Current Noise Density: 0.5fA/√Hz

♦ Low Distortion: 0.0002% THD (1kΩ load)

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.

♦ 400µA Quiescent Supply Current per Amplifier

♦ Single-Supply Operation from +2.4V to +5.5V

♦ Input Common-Mode Voltage Range Includes

Ground

♦ Outputs Swing within 8mV of Rails with a 10kΩ Load

For a d d itiona l p owe r c ons e rva tion, the MAX4249/

MAX4251/MAX4253/MAX4256 offer a low-power shut-

down mode that reduces supply current to 0.5µA and

puts the amplifiers’ outputs into a high-impedance state.

The MAX4249–MAX4257’s outputs swing rail-to-rail and

the ir inp ut c ommon-mod e volta g e ra ng e inc lud e s

ground. The MAX4250–MAX4254 are unity-gain stable;

the MAX4249/MAX4255/MAX4256/MAX4257 are internal-

ly compensated for gains of 10V/V or greater. The single

MAX4250/MAX4255 are available in a space-saving,

5-pin SOT23 package.

♦ 3MHz GBW Product, Unity-Gain Stable
