_______________General Description

The MAX4162/MAX4163/MAX4164 are single/dual/quad,
micropower operational amplifiers that combine an
exceptional bandwidth to power consumption ratio with
true rail-to-rail inputs and outputs. They consume a
mere 25µA quiescent current per amplifier, yet achieve
200kHz gain-bandwidth product and are unity-gain
stable while driving any capacitive load. The
MAX4162/MAX4163/MAX4164 operate from either a
single supply (+2.7V to +10V) or dual supplies (±1.35V
to ±5V), with an input common-mode voltage range that
extends 250mV

beyond

either supply rail. These ampli­fiers use a proprietary architecture to achieve a very
high input common-mode rejection ratio without the
mid-swing nonlinearities present in other Rail-to-Rail

®

op amps. This architecture also maintains high open­loop gain and output swing while driving substantial
loads.

The combination of excellent bandwidth/power perfor­mance, single-supply operation, and miniature footprint
makes these op amps ideal for portable equipment and
other low-power, single-supply applications. The single
MAX4162 is available in 8-pin SO and space-saving
5-pin SOT23 packages. The MAX4163 is available in an
8-pin µMAX or SO, while the MAX4164 comes in a
14-pin SO.

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
