_______________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

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.
