♦ 3MHz Gain-Bandwidth Product
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-

♦ +2.3V to +6.5V Single-Supply Operation
♦ Rail-to-Rail Input Common-Mode Voltage Range
♦ Rail-to-Rail Output Voltage Swing
♦ 250µV Offset Voltage

, and the outputs swing rail-to-rail. The MAX4331/
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
a nd othe r low-volta g e , s ing le -s up p ly a p p lic a tions .
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-
c is ion, low-volta g e d a ta -a c q uis ition s ys te ms . The
MAX4330 is available in the space-saving 5-pin SOT23
package, and the MAX4331/MAX4333 are offered in
a µMAX package.
♦ Low-Power, 9µA (per amp) Shutdown Mode
(MAX4331/MAX4333)
♦ No Phase Reversal for Overdriven Inputs
♦ Capable of Driving 2kΩ Loads
♦ Unity-Gain Stable
