Single/Dual/Quad, Low-Cost, Single-Supply,
Rail-to-Rail Op Amps with Shutdown
General Description
The MAX4480–MAX4483 low-cost, general-purpose op
amps offer Rail-to-Rail^® outputs, draw only 50µA of quies-
cent current, and operate from a single +2.5V to +5.5V
supply. For additional power conservation, the MAX4481
offers a low-power shutdown mode that reduces supply
current to 0.5µA (max) and puts the amplifier’s output in a
high-impedance state. These devices are unity-gain sta-
ble with capacitive loads up to 400pF. The MAX4480–
MAX4483 are specified to +125°C, making them suitable
for use in a variety of harsh environments, such as auto-
motive applications.
The MAX4480 is a single amplifier offered in a tiny 5-pin
SC70 package. The MAX4481 is a single amplifier with
a low-power shutdown mode that reduces supply cur-
rent to <0.5µA and comes in a 6-pin SC70 package.
The MAX4482 is a dual amplifier and comes in the
space-saving 8-pin SOT23 package. The MAX4483 is a
quad amplifier and comes in a 14-pin TSSOP package.
All devices are specified for operation across the -40°C
to +125°C automotive temperature range.
