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.
