Ultra-Small, +1.8V, µPower,

Rail-to-Rail I/O Op Amps

General Description

Features

The MAX4291/MAX4292/MAX4294 family of micropow-

er operational amplifiers operates from a +1.8V to

+5.5V single supply or 0.9V to 2.75V ꢀual supplies

ꢀ Ultra-Low Voltage Operation—Guaranteed Down

to +1.8V

ꢀ 100µA Supply Current per Amplifier

ꢀ 500kHz Gain-Bandwidth Product

anꢀ has Rail-to-Rail input/output capabilities. These

amplifiers proviꢀe a 500kHz gain-banꢀwiꢀth proꢀuct

anꢀ 120ꢀB open-loop voltage gain while using only

100µA of supply current per amplifier. The combination

of low input offset voltage ( 400µVꢁ anꢀ high-open-loop

gain makes them suitable for low-power/low-voltage

high-precision applications.

ꢀ 120dB Open-Loop Voltage Gain (R = 100kΩ)

ꢀ 0.017% THD + Noise at 1kHz

ꢀ Rail-to-Rail Input Common-Mode Range

ꢀ Rail-to-Rail Output Drives 2kΩ Load

ꢀ No Phase Reversal for Overdriven Inputs

ꢀ Unity-Gain Stable for Capacitive Loads up to 100pF

ꢀ 400µV Input Offset Voltage

The MAX4291/MAX4292/MAX4294 have an input com-

mon-moꢀe range that extenꢀs to each supply rail, anꢀ

their outputs typically swing within 20mV of the rails with

a 2kΩ loaꢀ. Although the minimum operating voltage is

specifieꢀ at +1.8V, these ꢀevices typically operate ꢀown

to +1.5V. The combination of ultra-low-voltage operation,

rail-to-rail inputs/output, anꢀ low-power consumption

makes these ꢀevices iꢀeal for any portable/two-cell bat-

tery-powereꢀ system.

ꢀ Single Available in Ultra-Small 5-Pin SC70

Dual Available in Space-Saving 8-Pin µMAX

The single MAX4291 is offereꢀ in an ultra-small 5-pin

SC70 package anꢀ the ꢀual MAX4292 is offereꢀ in a

space-saving 8-pin µMAX package.
