UCSP, Micropower, Single-Supply, 10V,
Rail-to-Rail I/O Op Amps
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
(2.5V to 10V) or dual supplies (±1.25V to ±5V), with an
input common-mode voltage range that extends 250mV
beyond either supply rail. These amplifiers use a propri-
etary architecture to achieve a very high input common-
mode rejection ratio without the midswing nonlinearities
present in other rail-to-rail op amps. This architecture
also maintains high open-loop gain and output swing
while driving substantial loads.
The combination of excellent bandwidth/power perfor-
mance, 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 ultra chip-scale package (UCSP™) and an 8-pin
µMAX
®
or SO package. The MAX4164 is available in a 14-
pin SO 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.
