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 2kΩ load with Rail-to-Rail
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.

Bypass the power supply with 0.1µF capacitor to ground. Good layout techniques optimize performance by decreasing the amount of stray capacitance at the op amp’s inputs and outputs. To decrease stray capaci- tance, minimize trace lengths by placing external com- ponents close to the op amp’ ...
