23/MAX164
General Description
Features
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.
♦ UCSP Package (MAX4163)
♦ 1.0pA Typical Input Bias Current
♦ Single-Supply Operation from 2.5V to 10V
♦ Input Common-Mode Voltage Range Extends
250mV Beyond Either Supply Rail
♦ Rail-to-Rail Output Swing
♦ 200kHz Gain-Bandwidth Product
♦ 25µA Quiescent Current per Amplifier
♦ Excellent CMRR, PSRR, and Gain Linearity
♦ No Phase Reversal for Overdriven Inputs
♦ Unity-Gain Stable
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
♦ Stable with Any Capacitive Load
♦ Internally Short-Circuit Protected to Either Rail
