General Description

The MAX4484/MAX4486/MAX4487 single/dual/quad low-

cost general-purpose op amps operate from a single

+2.7V to +5.5V supply. The op amps are unity-gain stable

with a 7MHz gain-bandwidth product, capable of driving

an external 2kΩ load with rail-to-rail output swing. The

amplifiers are stable with capacitive loads of up to 100pF.

The MAX4484/MAX4486/MAX4487 are specified from

-40°C to +125°C, making them suitable for a variety of

harsh environments.

The single MAX4484 is available in the ultra-small 5-pin

SC70, while the dual MAX4486 is packaged in the space-

saving 8-pin SOT23 and μMAXM packages. The quad

MAX4487 is available in the 14-pin SO and TSSOP pack-

ages.
