General Description

The MAX4330–MAX4334 single/dual/quad op amps

combine a wide 3MHz bandwidth, low-power operation,

and excellent DC accuracy with Rail-to-Rail® inputs and

outputs. These devices require only 245µA per amplifier,

and operate from either a single +2.3V to +6.5V supply

or dual ±1.15V to ±3.25V supplies. The input common-

MAX4333 feature a shutdown mode in which the output

goes high impedance and the supply current decreases

to 9µA per amplifier.

Low-power operation combined with rail-to-rail input

common-mode range and output swing makes these

amplifiers ideal for portable/battery-powered equipment

and other low-voltage, single-supply applications.

Although the minimum operating voltage is specified at

2.3V, these devices typically operate down to 2.0V. Low

offset voltage and high speed make these amplifiers

excellent choices for signal-conditioning stages in pre-

cision, low-voltage data-acquisition systems. The

MAX4330 is available in the space-saving 5-pin SOT23

package, and the MAX4331/MAX4333 are offered in

a µMAX package.
