MAX4162/MAX4163/
MAX4164
UCSP, Micropower, Single-Supply, 10V,
Rail-to-Rail I/O Op Amps
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 proprietary 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
● Stable with Any Capacitive Load
● Internally Short-Circuit Protected to Either Rail
The combination of excellent bandwidth/power performance,
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
