Single/Dual/Quad, Low-Cost, Single-Supply,
Rail-to-Rail Op Amps with Shutdown
General Description
The MAX4400–MAX4403 low-cost, general-purpose op
amps offer Rail-to-Rail
®
outputs, draw only 320µA of qui-
escent 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 environments,
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 and SO packages. The
MAX4403 quad amplifier is packaged in a 14-pin TSSOP
or SO.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
