General Description

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

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 2k

Ω 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.
