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 (+2.7V to +10V) or dual supplies (±1.35V
to ±5V), with an input common-mode voltage range that
extends 250mV beyond either supply rail. These ampli-
fiers 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 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 µMAX or SO, while the MAX4164 comes in a
14-pin SO.
