Single/Dual/Quad, Low-Cost, Single-Supply,
Rail-to-Rail Op Amps with Shutdown
–MAX403
General Description
Features
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 environments,
such as automotive applications.
