Single/Dual/Quad, Low-Cost, Single-Supply, Rail-to-Rail Op Amps with Shutdown
General DescriptionThe 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.

Electrical CharacteristicsStresses 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.
