General Description

The MAX4480–MAX4483 low-cost, general-purpose op

amps offer Rail-to-Rail

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.
