General Description

The MAX4484/MAX4486/MAX4487 single/dual/quad

low-cost general-purpose op amps operate from a sin-

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

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

driving an external 2k

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, such as automotive.

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 µMAX packages. The

quad MAX4487 is available in the 14-pin SO and

TSSOP packages.
