SOT23, Low-Noise, Low-Distortion, Wide-Band,

Rail-to-Rail Op Amps

General Description

Features

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.

ꢀ 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

ꢀ Input Common-Mode Voltage Range Includes

Ground

ꢀ Rail-to-Rail Output Swings with a 1kΩ Load

ꢀ 10MHz GBW Product, Unity-Gain Stable

(MAX4475–MAX4478)

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/MAX4489 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 packages.
