General Description

The MAX4480–MAX4483 low-cost, general-purpose op
amps offer Rail-to-Rail®outputs, draw only 50µA of quies­cent 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 sta­ble 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 auto­motive 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 cur­rent 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.

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.
