Low-Cost, High-Slew-Rate,

Rail-to-Rail I/O Op Amps in SC70

General Description

Features

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 sup-

ply or dual 1.ꢀ5V 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 ꢀ00pF.

ꢀ 2.7V to 5.5V Single-Supply Operation

ꢀ 10V/µs Slew Rate

ꢀ Rail-to-Rail Input Common-Mode Voltage Range

ꢀ Rail-to-Rail Output Voltage Swing

ꢀ 10MHz Gain-Bandwidth Product

ꢀ Unity-Gain Stable with Capacitive Loads

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

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

SOT2ꢀ package. Specifications for all parts are guaran-

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

ture range.
