General Description

The MAX4400–MAX4403 low-cost, general-purpose op

amps offer rail-to-rail outputs, draw only 320µA of quies-

cent current, and operate from a single +2.5V to +5.5V

supply. For additional power conservation, the MAX4401

offers a low-power shutdown mode that reduces supply

current to 1µA (max) and puts the amplifier’s output in

a high-impedance state. These devices deliver ±1.4mA

of output current and are unity-gain stable with a 1MHz

gain-bandwidth product driving capacitive loads up to

400pF. The MAX4400–MAX4403 are specified to +125°C,

making them suitable for use in a variety of harsh environ-

ments, such as automotive applications.

The MAX4400 single amplifier is available in ultra-small

5-pin SC70 and space-saving 5-pin SOT23 packages.

The single MAX4401 includes the shutdown feature and

is available in a 6-pin SC70. The MAX4402 is a dual

amplifier available in 8-pin SOT23, µMAX®, and SO

packages. The MAX4403 quad amplifier is packaged in a

14-pin TSSOP or SO.
