MAX4475–MAX4478/MAX4488/MAX4489  
SOT23, Low-Noise, Low-Distortion,  
Wide-Band, Rail-to-Rail Op Amps  
General Description  
Features  
o Low Input Voltage-Noise Density: 4.5nV/Hz  
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.  
o Low Input Current-Noise Density: 0.5fA/Hz  
o Low Distortion: 0.0002% THD+N (1kload)  
o Single-Supply Operation from +2.7V to +5.5V  
o Input Common-Mode Voltage Range Includes  
Ground  
o Rail-to-Rail Output Swings with a 1kLoad  
o 10MHz GBW Product, Unity-Gain Stable  
(MAX4475–MAX4478)  
o 42MHz GBW Product, Stable with A +5V/V  
For power conservation, the MAX4475/MAX4488 offer a  
low-power shutdown mode that reduces supply current  
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 compensated  
for gains of +5V/V or greater with a gain-bandwidth  
product of 42MHz. The single MAX4475/MAX4476/  
MAX4488 are available in space-saving, 6-pin SOT23  
and TDFN packages.
