MAX4400–MAX4403
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 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.
