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

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.

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-sav-

ing 8-pin SOT23 or μMAX® 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.
