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.
