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

pin SO package.
