MAX4475–MAX4478/  
MAX4488/MAX4489  
SOT23, Low-Noise, Low-Distortion,  
Wide-Band, Rail-to-Rail Op Amps  
General Description  
Features  
● Low Input Voltage-Noise Density: 4.5nV/√Hz  
● Low Input Current-Noise Density: 0.5fA/√Hz  
● Low Distortion: 0.0002% THD+N (1kΩ load)  
● Single-Supply Operation from +2.7V to +5.5V  
The MAX4475–MAX4478/MAX4488/MAX4489 wide-  
band, low-noise, low-distortion operational amplifiers  
offer rail-to-rail outputs and single-supply operation  
down to 2.7V. They draw 2.2mA of quiescent supply  
current per amplifier while featuring ultra-low distortion  
(0.0002% THD+N), as well as low input voltage-noise  
density (4.5nV/√Hz) and low input current-noise density  
(0.5fA/√Hz). These features make the devices an ideal  
choice for applications that require low distortion and/or  
low noise.  
● Input Common-Mode Voltage Range Includes  
Ground  
● Rail-to-Rail Output Swings with a 1kΩ Load  
● 10MHz GBW Product, Unity-Gain Stable  
(MAX4475–MAX4478)  
● 42MHz GBW Product, Stable with AV ≥ +5V/V  
(MAX4488/MAX4489)  
For power conservation, the MAX4475/MAX4488 offer  
a low-power shutdown mode that reduces supply cur-  
rent to 0.01µA and places the amplifiers’ outputs into a  
high-impedance state. These amplifiers have outputs  
which swing rail-to-rail and their input common-mode  
voltage range includes ground. The MAX4475–MAX4478  
are unity-gain stable with a gain-bandwidth product  
of 10MHz. The MAX4488/4489 are internally compen-  
sated for gains of +5V/V or greater with a gain-band-  
width product of 42MHz. The single MAX4475/MAX4476/  
MAX4488 are available in space-saving, 6-pin SOT23  
and TDFN packages.
