MAX4470EUK General Description

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 current,

low-operating voltage, and rail-to-rail output capabilities

make these operational amplifiers ideal for use

in single lithium ion (Li+), or two-cell NiCd or alkaline

battery systems.
