Low-Cost, High-Slew-Rate,
Rail-to-Rail I/O Op Amps in SC70
General Description
The MAX4490/MAX4491/MAX4492 single/dual/quad,
low-cost CMOS op amps feature Rail-to-Rail^® input and
output capability from either a single +2.7V to +5.5V
supply or dual ±1.35V to ±2.75V supplies. These ampli-
fiers exhibit a high slew rate of 10V/µs and a gain-band-
width 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.
