Single/Dual/Quad, Low-Power, Single-Supply,
Rail-to-Rail I/O Op Amps with Shutdown
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-
mode voltage range extends 250mV beyond V
EE
and
V
CC
, 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
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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
