Rail-to-Rail Op Amps

General Description  
Features  
The MAX4464/MAX4470/MAX4471/MAX4472/MAX4474  
family of micropower op amps operate from a single  
+1.8V to +5.5V supply and draw only 750nA of supply  
current. The MAX4470 family feature ground-sensing  
inputs and rail-to-rail output. The ultra-low supply cur-  
rent, low-operating voltage, and rail-to-rail output capa-  
bilities make these operational amplifiers ideal for use  
in single lithium ion (Li+), or two-cell NiCd or alkaline  
battery systems.  
o Ultra-Low 750nA Supply Current Per Amplifier  
o Ultra-Low +1.8V Supply Voltage Operation  
o Ground-Sensing Input Common-Mode Range  
o Outputs Swing Rail-to-Rail  
o Outputs Source and Sink 11mA of Load Current  
o No Phase Reversal for Overdriven Inputs  
o High 120dB Open-Loop Voltage Gain  
o Low 500µV Input Offset Voltage  
The rail-to-rail output stage of the MAX4464/MAX4470/  
MAX4471/MAX4472/MAX4474 amplifiers is capable of  
driving the output voltage to within 4mV of the rail with a  
100kload, and can sink and source 11mA with a +5V  
supply. These amplifiers are available in both fully com-  
pensated and decompensated versions. The single  
MAX4470, dual MAX4471, and the quad MAX4472 are  
unity-gain stable. The single MAX4464 and the dual  
MAX4474 are stable for closed-loop gain configurations  
of +5V/V. These amplifiers are available in space-sav-  
ing WLP, SC70, SOT23, µMAX®, and TSSOP packages.  
o 9kHz Gain-Bandwidth Product  
(MAX4470/MAX4471/MAX4472)  
o 40kHz Gain-Bandwidth Product  
(MAX4464/MAX4474)  
o 250pF (min) Capacitive Load Capability  
o Available in Tiny, 6-Bump WLP, 5-Pin SC70, and  
8-Pin SOT23 Packages
