The MAX4490/MAX4491/MAX4492 single/dual/quad,

low-cost CMOS op amps feature Rail-to-Rail

output capability from either a single 2.7V to 5.5V sup-

ply or dual ±1.35V to ±2.75V supplies. These amplifiers

exhibit a high slew rate of 10V/µs and a gain-bandwidth

product of 10MHz. They can drive 2kΩ resistive loads

to within 55mV of either supply rail and remain unity-

gain stable with capacitive loads up to 300pF.

The MAX4490 is offered in the ultra-small, 5-pin SC70

package, which is 50% smaller than the standard 5-pin

SOT23 package. Specifications for all parts are guaran-

teed over the automotive (-40°C to +125°C) tempera-

ture range.
